[Boatanchors] AM-8C/TRA-1 amp power supply info needed...

[WE0H]

Does anyone know what voltages the screen & plate are for this 
amplifier? I am modifying one for 600 meters and have no clue what I 
need to build for a screen supply or what voltage the amp should have on 
the plates.

Would it be as simple as using the tube datasheet suggested voltages for 
the class of operation it will be setup for?

Thanks much,
Mike
