Help for Hammarlund Super Pro
I am in the process of building a power supply for my Superpro SP-400-X, and
I am bit surprised of the voltages I read on the original power supply
schematic diagram.
The voltage feeding the audio amplifier (two 6F6s in push-pull) is 380V,
which looks quite high to me.
Does someone know whether the voltages shown on the diagram are open-circuit
or under load?
Thanks and 73
