Bought the oscillator coil and tuning knob from Marty's parts set and it arrived today !

Installed coil and with slight adjustment radio seemed to work well, but not what I expected. Just happened to touch an area of PCB bottom near RF amp and signal level increased dramatically---puzzled by this, touched components in area on topside and heard some scratching, then same result ! Turned out that the RF transistor emitter resistor had a bad solder connection from factory---wiggling it would cause level to fall & rise greatly... The lead pulled right out of solder-filled plated through hole and appeared to have a thin coating of dried flux on it---probably has never worked correctly since new !

Thanks again, Marty !

More to come...

John
