I finally got the manual in my hands. I've scanned only the schematic into pdf format so far. It is too large to post here. I think if I try to reduce the resolution to post it, it will probably be unreadable. Anyway, there are 3 selenium rectifiers in the power supply labeled X1,X2, X3. The only reference to them in the parts list is Part-No 130-044 rated at 400 mA. Is there a suitable silicon diode that I can use to replace them, when I am doing a re-cap on the set ? I am familiar with the voltage increase using a silicon replacement. Do I need to use a resistor in series with them to drop the voltage back to what the selenium part would produce ? The only other "modern" components in the set is a pair of matched IN34 Germanium Diodes in the Phase Discriminator (Horizontal Oscillator) sync circuit.
