Joelt,
Let say I read the WE data one more time to be sure.
At 130V on plate with 360 ohm cathode resistor 417A draw 23mA.
That mean for me bias at 8.28V.
Now that mean we be safe to use even 1:3 step-up input trafo.
1:3 step-up give as 3 x 44 = gain of 132.
So now tell me it's 100V peak-to-peak it's possible from one tube
or not ??????????????
Joe
