    I'm trying to repair a switching power supply circa 1983. Yosio Electic
    Company Ltd. of Japan.

    The section in question is the +- 12vdc card. It uses a large number of
    glass diodes. Orange on the inside of the glass and a green ring at the
    anode with a yellow inner ring. No markings and I have no diagrams.
    Voltage in this area around 100volts DC.

    Should I assume a high speed switching diode good for 200 volts will
