Hello Mael,

I read your Posts and would suggest that you locate a Manual and Schematic with Transistor Audio Output.
Let me know if you have a better schematic with a non-IC audio circuit.
If not, I will try to find something like that for you to use.

If there is no schematic, then I should be able to find a typical 2 transistor output, audio amp schematic. Most audio amps in the 3 to 5 watt range are reasonably similar.

We can then look at the DC Supply voltages at the Audio Amp.

My first thought is that the large capacitor between the Collector(s) and the Speaker is leaking. That will cause oscillation and squeal.

Keep me posted. I will assist where I can.
A picture of your audio amp board would help also

Hello All,

I have been enjoying Buddy's Video's on YT for the last week. We have so much in common - it seems.
Located near Athens, GA and licensed for 49 years with continuous Building and Repairing over the years.
I also enjoy RC Airplanes and Gliders - 45 years. I play Guitar and Pedal Steel for too many years to mention :)

I am currently just about to Retire from Work (a bit overdue) and start working on the Boat Anchor PILE!
A Clegg Interceptor Receiver is first in line.... yeah; its got the big Jackson Brothers Dial - Analog - Of course!

I hope to be a regular here; and Help and Enjoy my time on the Forum.

I would like to add a Service Monitor to my Bench. Something that I have always wanted and needed. But; I have gotten by without so far.

Best Wishes to All here!
