"humm"?... if I read your original post correctly francocleef, seems that you replaced all the other by-pass type condensers (caps-bakelight blocks) but didnt replace the "previously replaced" eclectrolytics? If so, those (electrolytics) were most likely subbed in place of the orig "missing orig electrolytics" several yrs ago also? Most modern type electrolytics are very small in comparison to the originals. Since you didnt replace those, why not try replacing them also?, ( following Rons correct polarity instructions)!! New 10 ufs @ 450 volts may be all you need to finish a full re-capping job? If the electrolytics you left in place are also older types, most likely they are bad also. Doesnt cost much to go ahead and replace those few electrolytics caps also to see if it rids the hum? Just a idea. Perhaps I read all this wrong? If so,please excuse me, as Im getting to be a old-f*rt these days!
