Re: Drake SW4A AGC issues part three


 

Just a guess, Mike, but you may have put a good cap in parallel with a leaky cap and ended up with a good leaky cap!

I may have simplified this¡­

when I was working on the receiver, I tack soldered some electrolytic capacitors in the power supply, still had the distortion. New cap came in, removed the ones I used to check operation and the distortion is now gone.

That¡¯s the mystery. Why would I have the distortion with caps I tack soldered into the circuit yet when I replaced the can (with the old caps) the distortion went away.
