My homebuilt HT-37 uses diode boards in place of the vacuum tube rectifiers so that is definitely an option. My overall supply is not the original Hallicrafters design though. Uses a large TV transformer from the junkbox and the "economy power supply" circuit to get HV and low B+. Also eliminated the swinging choke needed for the tube circuit.

It's actually not necessary to restore this transformer.? I just need to not use the 5V winding.? That might be as easy as stuffing a couple diodes into the socket where the HV rectifier used to be.? I could probably hook the 5V winding in series with the primary to reduce the output voltage a bit. Cheers Halden VE7UTS
