Power requirements for the WS-19 ser
The 19 set needs 12 volts to heat the filiments in the valves.
250 volts to operate the receiver and 550 volts to transmit. If you bulit a mains pwr supply in the case have a frame built up that can slide in the box. I would modify the schematic to inculde an indicator light (12v) and maybe a fan for cooling. The MK II needs 10 amps constantely regardless of receiving or transmitting, the MK III runs at a much lower amperage till you key the mike.
