[AMRadio] 575A / 673 tubes

[Patrick Jankowiak]

Speaking of which..

For my own sanity, I need to convert the KW from a pair of FWCT 
rectifiers to a pair of bridge rectifiers.

This will get me from having to carefully balance two variacs to 
equalize the voltages on both plate transformers, each of which is 
'half' the total secondary.

This will get me to a place where I can set he PA and modulator plate 
voltages separately, one with each variac.

I am looking for four 575A/673 tubes, four sockets for them, and four 
filament transformers rated 5V at 10A and 7500 volts or better insulation.

I don't want to go to solid state for the bottom half of the bridges.
