To whomever is interested,
Since I couldn't find any datasheet with tube specs for this tube, I thought I'd post some info for others who may be contemplating using these tubes (since they are advertised as being able to handle higher voltages).
I have one in a SE homebuilt job, and this is currently what the readings are under load.
I am using a NOS 5Y3GT rectifier (Toshiba).
PT secondary = 290VDC on each side (318 without a load) to ground
B+ = 368VDC to ground
Plate = 363-364VDC to ground
Screen = 302-303VDC to ground
Plate to Cathode = 343-344VDC
I have yet to see any smoke or red-plating. I'll keep you posted
