I just put an American Bosch Magneto Corp. Model 58 on the work bench. All I have to go by is a schematic, that I got on-line. It isn't the best but that is all I have to go by. If anyone out there has a schematic, a parts layout or any other info, on this radio, it sure would be helpful.
There is a large black box on the underside, of the P/S amplifier section, opposite the power transformer I believe this would be the filter capacitor bank. If this is the filter capacitors how likely are these to go bad, since they are encased in a tar substance?
Since this is only my second restore and help or info would be greatly appreciated.
