This is exactly why everyone expects that Shango can fix anything. I get the same reaction from my wife after successfully repairing stuff anyone else would simply toss into the nearest dumpster.
@shango066 Thank you so much again for fixing this radio for me! It will definitely be enjoyed. By the way, the reason the FM section was noisy is because the antenna wire was never reattached - I soldered it back on and it is much quieter now!
These are really nice, solid radios. I sent Shango some photos of the top on the one I have, so hopefully he can forward them to you, if you would like to recreate the letters for the band selector buttons. Strange this is missing on yours.
@@bountyhunter4885 Of course, Google blocked the link I tried to post here to a Google photo album I uploaded with photos of the top of this radio. Amazing... Google even ban links to their own web pages!
21:58 There are an average of 131 spiders per square meter around the globe. In ideal conditions, the density can reach up to 1000 spiders per square meter.
Paused at the 30:28 mark to comment. Thanks Shango for fixing this young man's radio for him, that's a nice piece and thanks for bringing some enjoyment to us on this Saturday afternoon.
Interesting to learn this was made for the Italian market. I have the same radio in great condition like this one, in Canada. Very impressive to see two large ferrite bar antennas; I haven't opened the one I have, since it works well. I e-mailed you some photos of the top to show how the buttons should be labeled, in case the owner wants to recreate the labels. The Sanyo AC power cord has a very small plug and socket compared with with average 'boombox' power cord.
One of the ferrite bars is for the lower "tropical" shortwave bands. It was pretty much standard fare in multibands at the time. The belts and slug tuned FM was not so common. Cheers!
Those tooth tuning belt systems are just maddening as anyone who's had a Transoceanic R7000, -1 will recall. I've got to look into that little generator / spectrum analyzer for my bench now.
Sanyo made also a version for the US, branded as Craig, model 1306. I'm pretty sure I've seen other versions as well, but I can't remember the brands. Another observation: it looks to me like the new belts were 3-d printed, which is pretty cool. Finally, the day the video was published was apparently Sanyo day - I bought and fixed a 1979 Sanyo M9922LU boombox.
@@tarstarkusz I had a small reel-to-reel branded as Craig in the late 60s. It was known for having a decent automatic level control and seemed to be high quality. We used it to tape our band practice so it got a lot of use. Later, it became a junk brand.
@@defaultuserid1559 I know there were a few name brands, even from America that were good quality at one time and then became the worst of the worst by the mid 80s.
That ebay belt looks like it's 3D printed with thermoplastic urethane (TPU). 49:10, "Anything, Anything" by Dramarama, great song, haven't heard it in probably a decade!
A very cool vintage radio well worth whatever price the owner ( wforkner) thinks should be made to get it up and working again. So after getting the belts Shango does the right thing and uses a set frequency to adjust the pointer to each tuner when putting on the new belts. Brilliant.
3D printing and the mechanical stuff is also not my favourite thing to do, but after some time, you realise it's the only way to become independent from sellers (charging lots of money for vintage or rare parts) and people doing mechanics (you gotta pay for those work hours and they are not cheap). This belt I guess would be TPE 3D printing or something like that. I learned to do repairs on cars and vintage radios came later after I got a 3D printer and other tooling. Learning to do CAD for 3D printing also came helpful in job searches, it's always nice to have some backup, just in case. Show off some skills in front of the people and they know you can get things done, you don't get any extra questions.
I guess you can say this radio was meant to be used. Let it sit and those belts will take memory and break. So I would "exercise" the tuners once a month parking in different positions on the dial to prevent "belt memory"
Shortwave still has plenty of life in it. You just need a good outdoor longwire antenna and a location away from RFI sources. An active loop like the MLA-30+ will work wonders too. In my California high desert location I routinely get plenty of shortwave broadcasts. Even the BBC and VOA in English. At night on the 19 meter band I can get the BBC, VOA and Radio New Zealand Int. loud and clear right next to each other on the dial. Almost like in the cold war days!
The TinySA has also been a very useful tool here for alignments. Worth every penny. Just make sure it's not a knockoff. (for those who want one). This looks like it has the potential for excellent weak signal DX. I would make a 455KHz BFO for SSB/CW decoding and install that inside. 73
Hmmm. Now *that* is good thinking. I don't understand why Shango says "SW is dead." Sure....it's not like in the 60's/70's/80's etc. but when the net went live that was *always* the line being promoted. It isn't *dead.* SW being SW you have to know when and where to monitor etc. You better make sure (IMO) you have a nice long wire or sloper type of antenna and GROUND GROUND GROUND everything. But it isn't dead. Your take?
@@MrPocketfullOfSteel I read your comment and I'm reminded of BBC Singapore which I used to listen to every morning at 11.685 MHz it went down for the count July 16th the only way to listen to BBC now at least in California if the jump on a WebSDR. Very sad
Great repair, that Sanyo’s a beaut! I love build quality and the tone (from what I can hear on this side). I’ve seen those cog style belts on a lot of lab equipment and of course Dual turntables (for the pitch control), the trick is getting the right tooth count I guess.
as a former DX-er / Shortwave band listener / scanner, I truly enjoyed this episode. Respect!!. My parents have a similar multi-band set from my childhood 70s, which is a think is a lot better, a National Panasonic, never needed servicing (yet).
Another good video. Especially like the comments about the "reporters" with their fear agenda who have breaking news about extreme heat in summer. These are the same people who rant about extreme cold in winter.
Dear Shang066, You have done an excellant job on this radio, and sounds just as good. I so much enjoy your video, you seem so pleasant. Have a good day.
Here in the UK the FM band is 88 - 108Mc, way back in the valve era it used to be 88 - 100Mc, some sets go down to 87.5Mc. The stereo subcarrier is 38kc, and the Rds data is 56kc.or thereabouts.
7:30 You could drill a tiny hole in each sprocket and one in the large wheel, then just string them together with dial cord, using the tiny holes both to apply spring tension and to keep all 3 wheels in alignment. It would be a pain getting them to align in the first place, but once aligned, the holes and springs would keep them that way. PS: That's surprisingly modern looking on the inside, with the cog belts, part of the chassis being made of plastic and the ceramic magnet speaker. Sanyo was ahead of its time.
Nice job on replacing those belts. I have the exact same spectrum analyzer, and for the money can't be beat especially since it can generate those signals..
I'll stick to my trusty old Radio Shack DX-402/Sangean ATS-505, thank you very much. I love the sensitivity on that set and did the mod to remove the split second silence when tuning up or down the bands. So, it's wide open listening while turning the tuning dial.
@@vcv6560 The DX-400 is nearly identical to the Uniden CR-2021 (the only difference is the Uniden uses an LED readout for the signal strength). It uses a different microprocessor/micro-controller chip (IC 501 or IC 601; TWP47C-something). I have no idea who makes the chip. It, unfortunately, does not match the one used in the DX-402/Sangean ATS-505 (various revisions) nor is it pin compatible. The DX-402 uses a Toshiba TC9327F 4-bit micro-controller, which also is used in the Roberts R9914 SW receiver. I don't know who makes the chip in the DX-400 or how to solve the same issue on that model.
I believe timing belts are called that not because they're used in the cam timing of an engine, but because they were created for timing purposes. So any toothed belt can be called a timing belt
That's the big problem with trying to repair older radios. The radio itself is robust, just rubber and certain plastic items are victims to the ravages of time. Many of these parts are long out of production and /or the companies are defunct, thats why 3D printers are so great, you can piece together the ild part good enough to get a scan of it, and make a new one. And with the variety of types of plastic available, you are sure to find one that will fit a particular application
Shango my first thought was cleaning spray got all over the oscillator coils and tuning components and completely detuned everything it happened to me with a Motorola console with a good working FM tuner and all I wanted to do is spray the tube socket and after that it stopped working. I had to wash it with a bunch of 91% alcohol with a spray bottle and let it evaporate then it came back. AM is not that critical and can tolerate cleaning spray but might loose a little sensitivity.
Good idea. I remember having to replace one of those small belts on a vacuum beater brush when it broke. One of those could be a close enough match to get one of these radios going again.
3D printing is neat. I designed a couple of adapters to slip on ends of an 18650 lithium cell, so it could replace a couple of D batteries in series. D batteries are friggin' expensive and I could reuse some 18650s that I have in abundance from old laptop batteries. 2 diodes in series with 2x18650s drop voltage to usual "4xD battery" levels, but radio would've probably worked with sligtht overvoltage all the same. And I had to recap and realign the radio first :^)
@@tarstarkusz It was more of a fun little evening project for me, really; considering that a "dumb" analog transistor radio isn't very picky about a power source as long as it stays in a certain voltage ballpark. But, having spent time making the model, I can now easily run my portable tape deck with 2 18650s too :^) I used to print AA->C/D sleeves from thingiverse too; considering that someone already had sunk some of their time to make a model, it's sometimes quicker just to print it at home for peanuts than to order it from some store or go looking for it locally.
@@ZXRulezzz The only problem with using lithium ion cells in an application like a radio is there is no over-discharge protection. Lithium cells hate being deeply discharged down to 0 (IIRC, it's around 2.5vpc). As much as I wouldn't mind having a 3d printer, I really have very little use for one. But it is one of those things where when you need it, it's a lifesaver. Shango could have used one to save the customer 40 bucks plus shipping here. One thing you can do besides 3d print is to cast and mold. If you have a part that has broken in half, you can glue it back together, take a silicone mold of it and then cast a new part with resin. This works VERY well. But it would be a bit expensive to do this for a battery adapter.
@shango066 I tried to rescue one of these from the garbage back in '89 already. Unfortunately all I got was circuit boards and the front. Could never get it to work anyways.
Crazy glue the belt tips together. Silicone a strong rubber belt around the outside edge. Overlap ends , and use silicone rubber sealant only. It will work even as cracks accumulate.
Cogged belts typical in small machinery. Printers, EDM machies. Probably in metric dimensions. Measure pitch or width and distance or pitch between teeth, overall circumference, I have a small box of cogged belts at the shop. I'll have to take a closer look at them. Could possibly make one from rubber o-ring? Right inner diameter and try to cut the teeth? 32:50 possibly the o-ring is a poor idea. Better than nothing. Anyway, great radio and nice repair efforts. 38:00 tuning meter inoperative or low signal level in radio? Antenna up?
I would HAPPILY drive 100 miles to purchase one of your televisions. Problem is that you're in Cali and I'm in Tenn. Can't afford to undertake such a task. Did drive to Chicago once though to pick up a Motorola 6y console tube radio. Needed parts to restore my grandmother's 6y, and that was the way to do it. Got it going too. Sitting in my living room. I'd love to have a color tube TV sitting right next to it, but such is life. The market for that type of thing around here is slim to none.
I’ve more often seen the Craig version of this radio, which I believe has a green cabinet. I suspect most of these Sanyo branded radios were sold outside of the US as a lower cost alternative to the Sonys and also to European Brands such as Grundig. The buttons or the panel beneath them were probably identified by markings or labels that fell off or wore off over the last 50 years. Perhaps an alignment or recapping would reduce the FM hiss and improve the radio’s overall performance. Keep in mind most of these multiband sets were designed to perform adequately but not to be DXing type radios, even if their high tech styling might lead you to think otherwise. Some of my older radios from this era are almost too sensitive on FM to be used in a large metropolitan area.
Teflon coated, stranded steel wire works for rigging small pulleys though I haven't tried it in a radio. It wouldn't work if the pulleys/rollers are small. These look just barely big enough for it to actually work. I'd get the wire with the thinner strands of course, so the wire wouldn't be too stiff, which of course results in springiness if the rollers are too small for the wire.
35:45 - the Europeans don't even try to nuance it like US media. I had Euronews on the TV and they said the G20 must act swiftly to reduce carbon and methane (due to the heatwave) but still we're unlikely to see results of those efforts for decades. All b.s.
The results in nature show up 10 to 40 years after any action has been put into effect or so I heard. Not even Corona caused a usable reduction in CO2 emissions, so yeah I agree.
You got way more AM and FM stations down in your parts then we got up in the SF bay of California. Sad radio dying in the SF bay part. And once we had alot of AM and FM stations.
