Hi folks. I have a Pioneer SX-600T. Mine is from 1966 and is in great shape but did not work when I got it. It smoked slightly and the main caps were leaking. I replaced the main caps, the bridge rectifier, and cleaned the controls. I was able to get FM out of the left channel but the right was very quiet and distorted. I recapped all the boards and now I have clean sound through the Aux input. AM is fine. FM mono and stereo are fine but are MUCH quieter than the Aux input, I mean way too quiet. FM Auto hums, and the hum changes with the volume. No reception at all. At this point I have replaced all the electrolytics and the oil caps, except the two caps on the AM board which I couldn't really get to and the two 100 uf 150v caps underneath that I have to order. There's a schematic for this but I don't have a service manual. Any thoughts?
