It's amazing how the plastic is so evenly yellowed and yet it hasn't lost its shine. I have a cheap guitar pedal in a plastic enclosure that's exactly this colour by design, and when I opened it to fix a bad connection it was white! They didn't even bother to get the right colour of plastic or paint it, they just "baked" it with UV...

Those small Sony radios work pretty well, for what they are. I have one that is radio only and it has very good reception and sounds decent, as good as those small speakers can. Nice to see that one back to life.

Dave, Thanks for doing this video. I've got several small portable radios similar to this and while they're still working fine, one day they probably won't. So your helpful video will give me an idea of where to look. Failing capacitors seem to be one of the biggest problems with old electronic gear. -Thomas

I got a 1987 Sony Dream machine at a thrift store, it has yellowed just as much.

I've found it fairly common to find shorted small electrolytics over the years. I remember a Fisher VCR where the video head preamp was passing signal from the heads. The capacitor was on the line feeding a voltage source to the head amp.

This usually is not due to exposing it to UV light. Those chemical formulars for plastics they used in the 80s and 90s contained special fire retardant additives that (over time) causes this yellowing of the plastics. This is reversible (to a certain degree) by exposing the plastic to direct sunlight (several hours to several days depending on the grade of yellowing). You can speed up this process by using hydrogen peroxide but it is in no way necessary.

would be nice to restore the cassette, so you can have it going too incase you have a tape to play on this unit. But I guess Radio is good enough! Great video. You seem to know where to look for the fault. Keep up the good work Dave!

I just started testing caps and when I got to that one I changed it. I don't have any cassettes that can play on it. Every old mix tape I have is recorded in dbx so it won't play anyway.

You know Dave you can unyellow the plastic with hydrogen peroxide. That if you wanted too take the thing apart ever . I had a sony radio which yellowed also .it the quality of plastic they use .

i thought if you use copywritten material as for "educational purposes" its fair use & you dont lose monetization? or did i mix that up?
@12voltvids2 ай бұрын
No such thing as educational purposes. Copy one of my videos and post it and see what happens. When Linus tech tips and fran Blanche used clips from my videos they had permission to use them. All the music I use I have permission. I got clipped by a bullshit claim for the 21 jump street music on my video about tape baking. Go listen to it now. The music has been scrubbed by AI.

Way too many lawyers that restrict the use of music, how can you troubleshoot beyond your private channel. I can see that everything has monetizing capability and can spot you, they should be worrying about making it better rather than squeezing a few bucks when they can

Yep - Those caps dont last and die eventually , I have a Yorx stereo portable that it decided to start humming { and yes it didn't know what to play} and one of the caps on the audio amp chip finally decided to call it quits - So like your video here changed it out and wha-La! its back in service, well now i need a source for new caps and I guess Lee's electronics is the last of the parts stores Or can you give me some idea where to look as Kamloops is no longer a source for parts.
