I was an electronics bench tech. You take for granted having the proper tools etc.. But that soldering iron needs to be proper! Bought one of those kits they sell and man that soldering iron almost ruined a simple bulb replacement. Nice videos, Thank You
Thanks for this. I just inspected all my 1983 Yamaha equipment and it looks great and sounds as it should. I bet my ears work at a level that I couldn't tell anyway lol. I have all the tools and half the skill, so I hope to find an easy one to fix someday.
Great videos, thank you for sharing your knowledge and experience! It is so rewarding to keep these wonderful masterpieces of HiFi engineering alive. At the age of 71, I look back at amplifiers and receivers I would have liked to have when I was young, but could not afford, and tbey are still running thanks to guys like you. Thank you.
Thank you so much Sir for your kind words. The equipment was engineered and built so well. I'm sure many of these units will be still operating when they are 100 years old.
hi everyone ,if anyone else wants to uncover computer pc repair try Saankramer Electronic Magazine System (just google it ) ? Ive heard some interesting things about it and my neighbor got cool success with it.
Love it. Good job! Just purchased a Sony STR-7055A...its so great and I want to be able to keep it running and sounding good. Your video just stated the process. Tks
I love that vacuum desoldering tool. Fantastic idea. I've just used those spring loaded ones or the bulbs. Neither are anywhere near as good on the circuit traces. You want to do it fast

Wonderful and informative video, I'm new to this, but I've seen some other videos like these, but yours is quite informative to watch, I'm planning to repair my old mini HiFi system, and like you said I manage to get it's servicing manual, Subscribed! 🙂
For a beginner like me , can you do a walk-through a average vintage amplifier schematic showing how the electricity flows. No one has done this ?. Cheers Matt U.K..
Gerald Weber can teach you. Look up his books on eBay and his videos are on pirate bay. I learned more from him in a few days then I learned the previous year and a half.
I'm about to order a new soldering iron probably going to find an analog model. Do you feel there is any advantage with a digital ? Just seems like more to fail
Had a question. Have you repair MD players? I have one that will power on when plugged into a power source but wont work on the original battery and the new battery I got for it. Think you could fix it?
Search RU-vid. There is someone posting up all the time fixing up vintage electronics of all sorts but solid state Knight stereo amps. I'll wait for that!
Thanks for sharing that information. Those tools are very basic. What other tools are necessary at an intermediate level? A variac? An oscilloscope? If so, does range matter? Signal generator? Test probes, jumpers, etc? I do have some electronic experience, but it's literally been decades. I'd like to get back into it, but not having the necessary tools is VERY frustrating. Any suggestions are greatly appreciated.
Your welcome, thanks for watching. Yes to all, LOL. I didn't see you mention a digital multi-meter. Just that can take you a long way. With a scope and meter you are 95% of the way there. A dim bulb tester is good to use and cheaper then a variac. If you google "dim bulb tester" there are many instructions on how to build one for a few dollars.
@@vintageaudioaddict thank you. Yes, I have a DVM, just forgot to mention it. I will look into the dim bulb tester. Thanks for responding, most don't seem to have the time. I agree with you regarding the solder removal tool. I still have a Soldapult spring loaded solder sucker, it works ok, but the tool you have looks to be far superior. Best regards.
Any suggestions regarding a scope? Back in the day, we all had Tektroniks on our benches, but that is probably out of my price range. Any cheaper ones that you might suggest?
@@redbike1986Hi, I been fixing audio equipment for many years, more than 40. Still have my first analog oscilloscope. The times are changing, now I have a digital Agilent scope and some Fluke multimeters I have one 28 series 2 and one 289. I bought one Rigol oscilloscope due the protocol sniffter, is posible to decode RS232, I2c, and various commun comunications protocols. Today is necesary a hot air station and powerful soldering iron, I bought one Yihua 150 watts high frecuency soldering iron and is wonderful. Lead free solder is a real problem without a powerful soldering. Cheers.
I have a optinica amplifier sm 1515b if the power transformer goes bad can it be fixed the part number is rtrnpo506afzz it is my graduation money purchase so it is centimental the output ic is s-60w sharp number rh-ix1066afzz the power cap. Is a dual 50 volt 6800mfd
Left out these needed tools: DVM, oscilloscope, source for service manuals/schematics, signal tracer, audio signal generator, side cutters, tweezers/forceps, and a host of other equipment if you plan on doing RF alignments.
Hello came across your channel.... Do you fix 90s .SONY DAT AUDUO PLAYERS....all parts are there... Just tape arm has come a loose...if so please can I get your address to send it to... Plus the drive belt is still good so that's a plus...thanks
@@vintageaudioaddict I have a Sansui 9090db that the right channel on all 3 speaker settings, doesn't work at all. Seemed like when I retrieved it from the dump 20 years ago, it would cut in and out before the red light of death would shut her down, but over the last few years when plugging it in after rediscovering it after moving or rearranging the basement, it doesn't work at all anymore. Do you have any recommendations for sourcing quality replacement parts, tips for troubleshooting/diagnostics, or parts you're interested in selling to help this here beginner revive the beast that solidified my passion for vintage audio from the Golden age? Any advice, tips or links to videos of yours would be greatly appreciated! Thanks for sharing your passion and expertise with the world!!!
Noway you live close to the state of Kentucky ? I would pay good for overhaul on G-8000 both driver boards and relay and power board I would love to get them overhauled something i wanna keep forever G-8000
It can't hurt, especially if the circuit traces are robust and not prone to lifting. If you reckon a solder join could go be prone to going dry, just refresh I'd say
I know that you didn't ask me, but I'll chime in here. I used to work as a technician and we bought a cheap "biscuit" fan that ran on 110v, put a cord on it and put it on our desk with the air being pulled away from us. This worked quite well. Also, after handling solder, don't smoke or eat without washing your hands. I hope this helps.
Do you have any idea what would make a fm tuner not pick up stations on a sansui g 9000 db, I can hear a faint signal on really strong stations but nothing strong enough to listen to. I have checked continuity going into the receiver but I don't know what to do next . Everything else works as it should.
Large filter caps another guy on RU-vid who restores vintage gear says says he seldom replaced them. He says it's not necessary as they often test good. Anyway I wonder what are your thoughts ?
Filter electrolytic caps can make problems in some circuits if they are bulging/swollen and/or if their ESR increases a lot. Then they are a good candidate for replacement, *Cheers!*
Please can you help me. I love my vintage audio so much, but people who did not know what they are doing have screwed everything up, done actual damage. I temporarily live in Pittsburgh area, but would bring my precious Polks and stackable turntable, Cd Players, tape deck, etc. to anyone who,knows how to get them back in shape. Or if you know anybody in this area, please recommend. The guys before cost me a fortune, told me I needed a needle, but no, it was a bent tone arm (not bent before they got hold of it) and didn't even know what a cartridge was). My life is so,sad without my music and I want it back. There is no way a digital speaker can ever produce the warm, emotionally deep music that comes out of LPs on an excellent turntable out of reverberating Polks. Bliss. Can you recommend someone to help. I don't care if they're in New York, if they can do the job. Thanks.
Hope you found one to fix your stuff. RU-vid is not the right place to ask questions as you can see this guy here doesn’t even consider you worthy of a reply. I’d suggest you google for some vintage Hi-Fi forums. There should be several that are knowledgeable and willing to help. Good luck🍀
When soldering using any tool please use a small fan to blow the fumes away from yourself. This is especially true for old lead/ tin solder. A face mask may fog up your glasses, mine are cheaters so yeah I'm old,, and you won't be able to see the very fine work your doing.
Not certain about the points made but ,if anyone else wants to discover ifixit and repair try Saankramer Electronic Magazine System (do a google search ) ? Ive heard some unbelievable things about it and my work buddy got excellent results with it.
You should instruct folks to remove that old "Sony bond" glue before reinstalling new caps. It becomes corrosive and will literally eat through the leads of thru hole components..
