for the driver tube. I know i can get a B+ of 300v for the driver stage.
As it stands now, i have 2 LEDs in series, which puts the 7a4 cathode at 3V. This also raised the Plate voltage to 115vdc.
I got some SS devices although i am not sure if they are rated for hi voltage. The ones i have are LR8N3G, TIP50, LM337, LM317HT. Can i make a CCS for the 7A4 plate with any of those. regards, Dak
