I worked the entire decade of the 1970's for a Magnavox dealer and serviced these sets daily. The transistors in the envelopes are post Philips takeover of Magnavox and carry the Philips part numbers which were the same for all Philips lines ie Sylvania and for a short time Philco. At the time we had a cross reference between the old and new part numbers. Magnavox transistor part numbers start with 61 usually the entire number is not printed on the transistor. I have a full set of Magnavox factory manuals. As far as the motors in the changers they are very robust and in all my time I never saw more than a handful bad, usually bearings worn out from lack of lubrication. The motors are 4 pole shaded pole induction motors. Contrary to what some have said in certain internet groups there are no permanent magnets in these motors.
@@krystinasaragos1535 The quickest way for me to identify the correct styllus for your unit would be to have a picture of the old stylus. If that's not possible a picture of the record changer would narrow it down to a couple of different stylii. If I have to go back to the manuals I'lll have to sort through many product guides to determine what changer your set used and then I'll need a run number to pick out the correct needle. Magnavox model numbers were almost usless to a Magnavox Technician since all of our service liturature was filled by the individual chassis numbers of the pieces that made up the unit ie radio chassis, record changer chassis etc. It can be done but it'll take a little time, But if I had to guess it would be a Magnavox part number 560345-1 or 557-DS77 available on ebay from a bunch of sellers. Good Luck

Very nice repair! That'll make a great radio. Side story, when my 95 year old neighbor died a few years back the family came in and dumped everything in his house with about 6 30 yard dumpsters. I dug through and found tons of old receipts, and things like service records and sales reciepts for his old late 20's early 30's car repairs from long gone car dealerships in my town. It was sad, I tried to save what I could.
I briefly worked for Goodwill a couple of years ago; we got people coming in and dumping tons of stuff from their parents' or grandparents' houses all the time - the stuff they couldn't sell on eBay or Craiglist, that is. And little known fact - Goodwill literally tosses about 80 percent of the donated stuff into the trash. Against rules, I fished a bunch of record albums out of the dumpster one day - you know, those old books of 78s. Not in the greatest of condition, but in one of them was a 12 inch record made in 1919. I lost that job because I dug that record out; they had a seriously demented policy about it, but damned if I was going to let a 100-year-old record go to the landfill. It wasn't even all that valuable; I see the very same records on eBay for like $10. Screw it, though. It was a minimum wage job, only a side job in the first place, and it technically wasn't 'theft' because it had been thrown in the garbage. I was pretty much done with the job anyway; it was depressing to see how a person's life can be so easily dismantled and sold off or discarded piece by piece. All in the name of a quick buck or two.

@@manFromPeterborough They're terrified that somebody might make a dollar and it NOT BE THEM. I've watched Goodwill intentionally destroy furniture, appliances, clothing, and other items based solely on 'we can't sell it'. Their policies are insane.

I rescued some antique records destined for the landfill, and in so doing deprived nobody. Of ANYTHING. I am so much better off not wasting my time in that s**thole.
@@xaenon I'm on good terms with the Lions centre, last Sat I saw a Bill Cosby record in the 18' skip, Garry the herder said "once it's in the bin, It's in the bin" .

The Magnavox Micromatic was actually one of the better changers made. They stayed a steady speed regardless of line voltage and they tracked very lightly in comparison to other changers of the day.
I also have one of these. Same year, same model, different design. It also came with all the original paperwork, and it works perfectly after 52 years. It's a very well made console.
I have my great aunt and uncle's unit. Just like this one. It's all but completely functional. It's enjoyable to listen to on Saturday night oldies or holiday records on the automatic changer.
Those amplifiers are great. Even though it may only be 5 watts per channel, they have plenty of gain. It will definitely drive a larger speaker. Thank you for posting.
Gary from VM parts carries most cartridges and Idler wheels for most turntables and record changers. He also rebuilds idler wheels that are no longer in stock
Amazing that you can still read everything on a receipt that was issued 50+ years ago. You can't do that with modern printed dockets - the ink fades after a year or so.
@@hom2fu Soy ink is just fine. It's thermal paper that's the problem, and it's always been prone to fade. The treehuggers may ruin a lot, but not everything is their fault.
You done a good job restoring this vintage MAGNAVOX STEREO. The one thing that I hated was the phonographs on some of those models back then. The most Notorious (not Notorious BIG the rapper) was BSR! The model on the one you worked on my phonograph did the same thing when it arrived in 1968, that was a DELMONICO small size console. It contained a section to hold a four way glasses holder & to the corner right an oval shaped opening to lower level for more glasses. A small luxury at that time for some of stereo systems. In 1982 future BSR models couldn't fit the previous one mounting holes cut outs. So I shopped for a replacement that would fit the 1968 concept it was GARRARD. It had slight teething problems. It did almost like the BSR did, not returning to automatic stop! It got worse the cartridge was not sending out any sound at all due to the receivers low power & watts. I returned it and with no experience with models built in the late 1960s the dealers and stereophonic sound testers weren't expertise at all. I read about this later in STEREO REVIEW someone experienced the same situation with the low powered metal cartridge way under 50 watts. Mine probably was 10 watts a channel. I still have a solid state of that model it was a replacement from the old vacuum tubes. What do you do if you wanted to play a much better quality turntable that can't send out enough power signals? I wouldn't want my records skipping or mis tracking! Some of them are replicas of later record players have had bad reviews they get stuck or in your phonographs case failing to go on the right size record or not returning when the record is finished! Any how this is inspirational I wish we had electronic stores again for a hobby 100% missed by yours truly! Longing to do models from the eras of 1968 to the mid 1990s. I'm restorating my late 1980s cabinets I custom built this and my 3 vintage models 2 DELMONICO'S & 1 JVC and a 1980s FISHER STUDIO STANDARD.On your phonograph it's probably the robotic mechanism or the screws you spotted may need to be replaced. There is another video on how to repair most models I saw it in 2020 very informative and for later use! Happy Hobbies & enjoy the music I'm glad I viewed. 👏👏👏👏👍👍
The good old days before polarized AC plugs. My 1968 Motorola Console has the same statement about “reversing the plug to get the least him”. Always enjoy your great videos and also love radiotvphononut’s videos too.
Awesome video! Loved how he kept the paperwork for the console, the purchase receipt and everything. Gives you a little history of it. Nice repair job, sounds great...except for what's coming out of the radio.
This brought me back to when I was 18 or 19. My neighbor (my 'best" friends mom) gave me her 66 or 67 Magnavox Astro Sonic Stereo Theater . It was double the length of yours, because it had a large color TV set mounted in the middle. It had the same large woofers and voice horns. It sounded great..but the tv didn't work. Everything was green. I should have kept it, but after spending a few hundred on non-existent "repairs'. I couldn't justify keeping it just for the stereo. It was so large ! Can't wait to hear this one !! peace
Two things to note that may help with this one or in the future: 1) You can use non-lubricating contact cleaner (MG Super Wash or the like) on the tuning cap, and then compressed air afterwards (keyboard duster or other low pressure methods). Cleans them right up and does not leave residue or "gum". 2) There is a pad circuit on the line input on most of those Mag consoles (right on the RCA jacks themselves), if you remove this, then you will get much greater sensitivity using external line level or headphone level devices. I do this as a standard mod on the consoles I restore at my shop. Happy fixing. Good work on this one.
Give the man a prize. My '68 Model 30 has exactly the same low sensitivity AUX input. I too use a bluetooth dingus. Caution: If you use a "quality" USB powered bluetooth gizmo like I did it produces a howl on the AM band that will blow your speakers out if you're not careful.
@@matthewdavies2057 Do you think it was the Bluetooth device itself, or possibly the crappy switching power supply they invariably provide with them? I've not had that issue with mine, but then, my Bluetooth receiver isn't located inside the unit. I'd love to eliminate the separate line boost I have to use with mine, can you describe this 'pad' circuit you mention? I don't recall seeing it in my '67.
@mathewdavies , the "howling" is likely a harmonic of the Bluetooth signal if the receiver is mounted too closely to the radio chassis. I have similar problems with cell phones and guitar amps in the studio. Or, as @xaenon suggested, I've had cheap AC to USB charger devices create nasty AC line leakage into the audio path in different scenarios. Both things to address. @xaenon , the pad is in the form of four resistors, mounted right to the RCA jacks on the jack terminal plate on the rear of the cabinet. It's an L configuration, so a resistor in series with the center pin and one from center pin to ground, on each channel. You can simply clip the ground-referenced resistor to increase the input impedance, therefore increasing sensitivity.
Shango, I envy you over the collared doves you have in your neighborhood :) A few years ago, I moved to live in my grandparents' apartment where I grew up, and since the neighborhood has become the end of downtown over the years, I doubt the collared doves will ever come back here since they don't deal with noise and odors from traffic. Not that I don't like magpies, ordinary pigeons and sparrows, but I miss the tender lullaby of the collared doves. The diamond or the strange triangle sign on the capacitor is Matsushita, in present Panasonic Corporation, formerly the parent company of the brands as National, Panasonic, Technics etc.
Another lovely informative video love your outlook, lifts my day. Had to laugh when the record deck kept playing what we in UK know as our National Anthem. Fine speaker set up.
You have that Maggie "Rockin'" now! The TT will be fine, used manually, these are great little consoles, when working. I used to have a few of them in different cabinets, a couple were solid state, and the others were tube type, all working well, I had to sell them and give them away about 6 years ago, to make room for some console TVs!😊
What a nice system, and that is why I'm watching your video.This model of Magnavox Asto Sonic was the first audio system that I purchased as a teenager in 1966. I loved the unit and enjoyed it for many years. The only issue I experienced was crackling in the resister pots which were replaced, and then failed again in a few years. The stylus was a wear item that was changed on a regular basis. My snobby friends chided me until bought high audio, then I got to experience some very expensive repair bills that go hand in hand with expensive audio systems.
Given Magnavox's long association with Phillips...many of their higher imperial product was regarded as the poor man's Fisher...Magnavox never changed from Jensen to Phillips speakers...Unfortunately, they never used a Phillips crossover...
I love these old units, i actually scored one like this myself today....A "His Masters Voice- Triad" Stereogram 3 in 1, I'm so excited to finally get one. Love you shango xxoo.
The following year they changed the design, losing the transformer coupled stage in the output, using a silicon NPN and Ge PNP output transistors. Measured 8 watts per channel using 8 or 4 ohm loads.
@@zulumax1 I think you mean Ge PNP outputs. The Chassis I had definitely had Si NPN and Ge PNP outputs. I copied the design on a bread board and it worked fine in this video: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-3DGte1Yrbd4.html
"i love putting together these puzzles that somebody else disassembled"... Without a trace of sarcasm, so do i. It's so much more rewarding than simply fixing something to have to build it & then diagnose. Looking forward to this.
This stereo is very similar to the one I have from my parents. The record changer looks identical to the changer in my unit. I had mine in for repair about a year and a half ago due to a low hum in radio and auxilary modes. It was due to six bad capacitors. Record changer was lubricated and works great. The only thing I have to do when playing records is let it run idle for about 2 to 5 minutes because there's a slight wow and flutter when it first starts up, but after it warms up and continues running; its perfect. No wow or flutter at all and according to the service technician when he tested it; the speed is dead on after it warms up from a cold start. Love the sound it has and also modified the external speaker set up by adding a terminal strip on the back with jumper wires coming from the original connectors for easier hookup. The only minor issue and not too concerned with it at this point; is the left channel in phono mode is softer than the right. Technician told me that the cartridge may eventually need replaced. I mostly use it for 78rpms and the special 16rpm background music records since they're mono anyway. I do play 33s and 45s ocassionally just to keep all the speeds working properly. Also put in a replacement pair of Quam 12" woofers at 8ohms. Had foam surround woofers in it before but they weren't giving the right sound. The Magnavox Quams sound better being they're a hard cone and designed for this type of unit.
You are a Life cycle assessment magician.Thank you for an Hour high quality education and Workmanship!! A little advice to make your own cleaning fluid.....i take Isopropyl alkohol and sprayoil i mixed it together (blow the oil into the isoprop with the sprayoil cannula, if its gonna slight milky its the right mixture) I used it for over 30years...the Alcohol cleans and the oil lubricated and makes a thin film to prevent oxydation. All the commercial sprays and cleaners are hydrophil and damage the rest of the circut very slowly.
Nice job on the restoration. I have the same changer as this one, but yours needs some adjustments. The tonearm had some slight issues in the auto cycle. There’s two screws on the right side of the tonearm is where you can adjust it to make it a lot better. The bottom screw is where you land on any size position might be 12”, 10” and 7” where a tonearm will tap the edge of the record, and the top screw will adjust the height to raise the tonearm a bit. I did these a few months ago after I got my stand-alone Magnavox Micromatic where it came out of a busted Magnavox Full Dimension portable stereo record player which was in a very poor shape. I cleaned it, lubricated, and everything works like a beauty. It has an auto shutoff switch after the last record, it rejects itself where the tonearm moves back and forth that there were no records left and then shuts off completely. These two screws which is on the right which is next to the tonearm where it needs adjustments. Magnavox made the best Astro Sonic consoles from that era, and it was originally in Fort Wayne, IN before it was bought by North American Philips company and turned into crap known as “Crapnavox”. During that time, they made the Odyssey, the very first video game console in 1972 where it featured a “Pong” game, and other games that has a collection of overlays to put on your CRT TV set to play a game, and that was an early experiment with a video game console.
I clean tuning capacitors with variable low power compressed air as a first step. A paint brush with fine bristles works great as a second step. Someone had a good comment about greaseless cleaner. Clean and grease the bearings but do not use oil. Oil will spread everywhere. I use wheel bearing grease that stays put. Some bent fins that you find are meant to be like that. Maybe Shango would like to comment on the purpose of the bent fins. Make sure none of the fins from the two parts are touching, of course. Great vid!
I have one from '67 and the original paperwork shows that the original owner made payments on it. Had it financed. I got it for 50 bucks. Sometimes they just got left behind when people would move because they are ungodly heavy.
Your experience mirrors mine. The original owner sold me his - complete with the owner's manual, platter card and ten-year diamond stylus hang tag, warranty card, sales agreement, and payment receipts. Same year as yours, even, and almost identical to the one in the vid (the only difference I can see is the cabinet trim). I paid $60 for mine and there was no indication it was ever opened up. Sounds gorgeous but it's starting to hum a little, so I figure it's probably time to get it serviced.
My parents had this exact same stereo back in the day, the bottom bass knob is where the power turns off and on turn the bass up higher for more power, this was a very nice sounding unit back in the day, actually we still have a 78 magna Vox console stereo in my home serves as a speaker system in our living hooked into our yamaha home theater
I just love seeing old repair orders, old credit card receipts, old advertising, anything old that's hand written that is from the mid to late 60 that's from the southern California area. I hope you get at least the record player operating and maybe spin some Bert Kaempfert songs on it.

For a bit of perspective, I signed on my hometown police department in 1973 after getting out of the army, took a cut in pay from my army salary to $400.00 per month as a rookie patrolman. That was enough to support my good wife and 2 kids with a place to live and food on the table. Not much more, we had an old beat up car I purchased when I was a soldier in Texas and a few sticks of furniture. I did have a small stereo that I picked up in Vietnam, but it was not much, of course we thought it was great back then. So that combo cost more back then than a months salary for a rookie cop.
Yay! a shango006 video! 👍👍 loved the comment "the type who believes the mains breaker will affects how the stereo sounds" :) Kudo for respecting this !👍👌😉
Good afternoon Shango great video buddy you have been a little slow coming out with new videos I look forward to your new videos when they come out you have a great day and a better night my friend
It almost looks like the record changer "thinks" that it has a 7" 45 rpm disk. You would have to disassemble the speed control and mechanical linkage to the tone arm to troubleshoot (not fun). I had to fix a few of these back in the day when the owners insisted on having a working changer. I agree with you that a modern manual turntable is infinitely superior if you care about the condition of your prized vinyl. Fedron can often restore old dried-up pinch rollers and phono disks. It was originally used to restore typewriter platens and other rubber parts. It's still available. Thanks for the great videos. Keeps old timers like me out of trouble during this pandemic.
My changer almost works, about 80% of the time it drops the needs too far from the record (a couple millimeters) and doesn’t track. Gonna fix it here soon somehow.
I used to have one of those. The sound quality is VASTLY improved if you cover the backs of the speakers with fiberglass. Actually, at one point, I had a stack of pizza boxes in mine. Any damping material will do, tho.
I have wondered about this. That big speaker with no resistance just billowing in open air. I considered boxing in the speaker compartments and experimenting with ports. I may play with that.
LOL! These things were the largest furniture in our house. Seriously, it was longer than our couch! We thought it was like having the New York Philharmonic in our house. Old 33's with scratches were so hip and cool!
I got one of those today for 30 bucks, One almost like it a model 3ST662A Ivory and it has the Imperial Micromatic with the fancy gold look to it and the big black arm with brush in front.. The unit itself is in immaculate shape in and out, the record player plays flawlessly with none of those issues like you were having BUT the AM FM radio does nothing at all, has just a hum. I can hook my 2 tube bluetooth with preamp to a set of the Rca jacks inside and it plays perfectly. Record player plays perfectly.. no AM FM I hope the set was worth 30 in excellent shape.
It's not that--it would only be off by a small amount if that were the case. This is a record sensor issue--something is gummed up with old grease. It looks like it might be setting down in the 7" position
@@justsumguy2u ding ding ding we have a winner! The jerky motion of the tone arm also suggests this is the second-design micromatic - the one that only detects the standard three sizes, versus the earlier model which would detect ANY size.
xaenon You’re right on the money! I have the same changer as this one. It works great after a full restoration. The tonearm detects the size of a record looks perfect, and the auto shutoff works after the tonearm tells you that there were no records left, and then shuts off.
Another point you said you clean the dial glass with water. Something I've done over the years on those is cover these in Gojo, leave it sit 10 minutes, then rinse it off. Amazing results. I've seen these glass dial covers so thirty with dirt, stuck on soft drink gunk, and even bird poop on a Stromberg Carlson table radio lol. This stuff cleans it all off.
Not long ago I fixed my Browni radio, this radio is somewhat have not to many information about it, probably it's rare (the full name of the radio is : Browni Hi Fi Super Deluxe , chassis or model number is: HT-8100 , made in 1962, in Japan)the old capacitors are dried but I changed those , this radio only have one band: MW Anyway good to see to you working on these old TV and radios and fix those at least there some people who are doing this (your videos have are so good)
Olá o receptor ficou beleza e agora só falta ajustar o mecanismo do toca disco. O gabinete é beleza uma ótima peça de decoração no ambiente. Abraço! Rio de Janeiro Brazil
Bloody hell ! thats 7 grand in pounds sterling today, and the first thing it played was God Save the Queen ! sounded like it, shame it wasn't the Pistol's version...cheers.
$395 in 1968 is worth $2980 today... wow! That portable TV was $602 in today's money. That guy really splashed out that day! In 1977 that repair would've cost him around $309 in today's dollars. So about 1/10th of its original cost.
What a beauty of a cabinet. I would have pulled a couple of those pots and thoroughly cleaned them. I think I would also have put in modern efficient speakers.. and possibly do two sets of 4 ohms in series per channel. Most of those caps you pulled weren't in that bad of shape. I think you should have changed the stylus as well. Over all, a good job. I also would have touched up the cabinet with some of Old English. Make em look new again.
My wife gifted me, this Christmas (and, she said combined with our 50th anniversary) a small HP Laptop, it's a neat little computer, and I do like it a lot. Extremely fine video boots extremely fast due to it's 1/2 TB solid state drive, instant on like the old Commodore 128. It comes with just a 1 year warrantee from HP, of course it keeps reminding me that for another 100 bucks I can extend that to 5 years (not happening!)
Since you're from California, and I've seen your other videos, I'm sure you've heard of Hoffman Stereo. I have a 1960 model, mahogany provincial, perfect shape. Sold new in my family, with all paperwork. I'd love you to see it.
I am astounded that one of those planes that seem to be constantly over head didn't fall out of the sky and on to your head for using McIntosh and Magnavox in the same sentence! The ONLY similarity between them would be that they both can be plugged into a wall outlet for power!
You can change the value of the line input impedance matching network resistors to accommodate the lower input signal level of the iPhone. Most of these Magnavox units had the input resistors mounted right on the input jack board where your hand was. Also those turntables are usually a breeze to fix and they're quite reliable, that one just has sticky grease on the size selector lever underneath. The arms don't track too terribly heavy, should be around 4 grams or less.
I am just finishing up on one of those Astro Sonic 40 consoles in Mediterranean. Full recap and changer restoration. Deep bass from the 15" woofers and while the changer would sound more impressive with a new cartridge, the original tracks well at 3 grams so wear is not an issue. True power on that series is about 10 w/ch as it was a couple steps up from the base level Astro Sonic.
I remember watching the power meters on 100W/channel receivers in the store, back in the day. The volume would be at room-filling, but not blasting level and the needle never went over 1/10 of a watt.
Nice, Magnavox always had this quality mystique. Well it was way better than a Symphonic! Did you check to make sure the pilot lamp on the front of the cabinet was working?
It’s the same thing they did with my Concord 220 reel-to-reel tape recorder that has all of the capacitors made by Matsushita/Panasonic, and it was a hybrid tube/solid state unit, and it was made in Japan for Concord. Concord made great reel-to-reel tape recorders during the 1960’s with Japanese components by Matsushita/Panasonic.
1:03:18 at the beginning you showed on the receipt it mentioned something about a door. It appears in this scene that wither the cabinet door was a different color, or it was repaired, and did not age the same color as the other door. The doors are a different color either way.
26:29 I worked on two cameras with a similar surface mount battery as your FLIR. One would not charge the removable battery because the surface mount battery was not taking a charge making a high resistance. The other would not turn on or take a firmware update while the surface mount battery measured 0.2 V. Seems like an easy way to build in planed obsolescence.
That's the reason why I prefer manual turntables and not the automatic ones. I Did a small restoration on a Dual 1019 for a friend last year. Very nice turntable. But all those wheels, gears, rubber idler wheel between the platter and the motor. It may will last another 15 - 20 years after lubricating but than it's done. Main cause? The rubber idler wheel. You are right Shango, just a 1200 (or another direct drive from Technics), or a Dual 505 or any other simple belt driven turntable. They will, when maintained properly (oil for the bearings and sometimes a new belt), last a lifetime.
11:40 I remember seeing a 1973 receipt for an Astro Sonic and that was only $339; it had better sound, with the Styrofoam speaker enclosures, but the cabinet was made of cheap plastic, looking like a Mediterranean-styled humidifier. Anyway, part of the price difference was probably due to the fact that it had real bass and treble controls; Magnavox always seemed to charge more for those freaky 4 position switches and the inexplicable "timber" control, their attempted solution to a non-problem.
Dave Here I know that Magnavox is regarded as the poor mans Fisher. I wonder if you could, one day, Do a broadcast repairing or restoring a Fisher console stereo...These days I'm an Audio Research /Magnapan owner, Thanks, I enjoy and learn much from your broadcasts,
It should track at "only" 3g. It is very easy to adjust. You just have to turn a knob on the rear of the tonearm. Once cleaned and relubed they are very good turntables. Stylus and replacement cartridges are available from V-M

That 1937 Co-Op is possibly the last one on Earth.Special model with only two grille teeth in front.
42:25 The Stereo Light on the 1966 Magnavox Astro Sonic Console here is radically brighter than yours. It has always been bright since bought new. The unit here has twin 15 inch speakers and the twin horns.
I WISH I lived close enough to adopt some of the stuff you have to offer from time to time. :( For example, I would LOVE to have something along the lines of a CTC-17, I have a 25er in near new condition in a CTC-90 right now that I really don't care about, I'd rather put the CRT in a vintage tube set. But I live too far away... Central Texas.
Maybe you could use a food temperature probe to check the surface temperature of components. I have no electronic background or knowledge but I enjoy your videos!
Those tuning meters get flaky/stick, the tuning cap will work OK all you need to do is put one drop of contact cleaner on the grounding wipers where they contact the rotor, only where the wipers contact the rotor shaft, then work the tuning back and forth, another problem I have seen is those knobs tend to split where the shaft pushes in, I make metal collars to put over them it's just PM to avoid the knob breaking, seen a number of these knobs broken over the years I think just due to pressure from rotation and stress that the shaft excerts from force fitting on to the knob.
That's a nice fix. It's hard to believe that only 5 or so watts will make the speaker grille fabric do that. I'm not quite sure if the audio level on those phones is a result of Samsung or Android, but I've had several Samsung phones and the output can be much louder than that before it goes to a much lower level if I do something to the phone. I haven't tried that on the Motorola phone I have, so I can't quite nail down the fault.
Since that record changer is a ceramic/crystal cartridge, that input could be used as a line input. That cartridge probably puts out 1-1.5V and there is no RIAA deemphasis on a ceramic/crystal phono stage, as RIAA was implemented for magnetic cartridges and the natural response of those nonmagnetic cartridges, for the most part, follows the curve. It might be a little tinny since if it was designed properly it would have about a 1 Megohm input impedance, but then again it might just be 47k like a line in.
i live in the country for years the expensive 240v submersible well pumps were burning out over & over. well drilling company always said it's the quality of the capacitor inside the unit. then one day (watching youtube videos) with my cheap multimeter i discovered at the square d breaker 1 leg was 123v the other was 93v. they had left one wire loose all those years cost piles of money/grief even having water trucked in with milk trucks to get water to 78 dairy cows
