[NJARC] Pinouts?

[antqradio at juno.com]

Assume that the 720 VAC transformer secondary is center tapped
for a full wave rectifier (80)?
720 / 2 = 360 VRMS
360 - 50 (for the loss in the rectifier) = 310 Vpeak
310 Vpeak X 0.636 = 197 VDC
Close enough?
Is there an inductor in the house?
Additional loss for electrostatic speaker field coil.

235 = 35?  Remote cutoff tetrode
224 = 24? Sharp cutoff tetrode
Then both are:
1= filament
2=plate
3=screen grid
4=cathode
5=filament 
cap=control grid

Regards,
Jim
