In Reply to: RE: Mike, that output stage supply operates at only 125VDC posted by Michael Samra on March 12, 2014 at 17:50:40:
The output tubes are 6AS7 or 6C33C. The plate voltage is only 125V. Two separate supplies are bridged, one for each phase of a fully balanced output. In addition, the amplifier has a completely separate bipolar HV supply that supplies the input and driver stages, with +/-300V, in his case.
