First Post on 37-620 restoration
#3

Thanks Codefox: I do have the schematic. I started replacing caps from the audio end first because I was waiting for my main filter caps. I've finished the audio and rf stages and am starting the power supply section now. So.... I can assume the schematic is correct and that is a 9K resistor?. This 37-620 is in a 37-650 cabinet. It looks like someone grafted the shadow meter from the old chassis on this one. I checked the circuit out and it looks like it might work. They removed the 10k resistor (R33) and put the shadowmeter leads there. That pretty well matches with the kind of circuit that the shadow meter came from in its original chassis. Anyway, this is an interesting radio to work on and I'm anxious to see how it performs. John
