Ok, went over any solder connections that looked iffy, removed and cleaned any flux overflow between foil traces, checked continuity from end to end of the foil traces, looking for breaks. Lastly, reflowed solder on the grounding points and tabs on the pcb and reflowed solder on the tuning gang on the circuit board, all futile. No oscillations yet. This set has always been in a heated living room I am told so can't imagine there's a moisture problem in the circuit board. I would be hesitant in trying to warm it in an oven for fear of warping plastic parts, especially the dial. I keep getting a nagging feeling that Q1, the osc transistor is critical. That is what led me to try 3 different transistors with no luck. The original Q1 did have collector to emitter leakage! The Sams parts list does have the ECG161 as a replacement. Maybe, if I could get an original Magnavox transistor that would work. I don't know if it's that critical. Anyway one last tidbit of info on this radio. According to the woman's son, he said the set never really played that great. I don't know what to think!!
