Poor Impulse Control
I bought a 500 on bartertown that had non functional AM and FM. I tested all the tubes - all good; replaced all the electrolytics (only 1 can section) and wax+paper caps; brought it up on variac and tested. I have reasonable voltage at all sections of the can capacitors. Plays great through AUX - sounds amazing. I get some bleed through on all other modes from aux - not sure this is normal.
So, neither the AM nor the FM work and there is no movement in the tuning meter. I am not sure what to look for - having very little tuner experience. I would guess the problem is where the two sections merge into the amplifier section, or have something to do with the 135V source for all the tuner section tubes. Looking for a schematic - not one on fisherconsoles.com
Smoke from my Oakland Deck - normally I can see about 15 miles to some distant hills
