Well done David, nice little fix. Contrary to earlier comments you can fix radios without a signal generator - I've done it. So many radios are given up as dead when many faults are dead simple. Battery terminals, dirty volume Pots / switches, broken wires, bad joints etc, etc.
Thanks - I've been enjoying fixing a few old radios during the various lockdowns. I've got another on the bench now, I should make a video for that one - it's missing just about everything.
It's not repaired. After you swapped the caps and retouched the solder joints there is still little volume. The amp is good because you could hear a decent output from the signal generator. Forget the signal generator you need a signal tracer. You havent found the problem.
FYI I start by spraying some cleaner into the band switch and vol control. Electrolytic capacitor kits are cheap buy them on eBay I usually just replace them. Loose and bad solder connections. Deoxit is good for cleaning.
It's a bit difficult to go into in a comment, but basically you're looking to see if the base is biased (has a voltage around half the supply voltage on it) and that there is voltage on the collector. Remember, most if not all germanium transistors you'll come across are PNP, so the emitter will be positive and the base & collector will be negative.
Dave would you have an idea to point me in the right direction volume on Jukebox Classic just turns itself to highest volume can happen when you first turn on or after been on for a few hrs..could you help me..please ..by pointing me in the right direction..thankyou Trevor
