In Reply to: Seeking advice .. Resistor loaded parafeed SE posted by C.Y on June 21, 2006 at 04:19:13:
2A3 - 595V before 5K R load, 300V on plate, 45V on cathode. I am happy the DC voltages are standard..
5842 - 330V before 17K R load, 140V on plate, 1.75V on cathode. I used 6AL5 tube diode bias, replacing cathode R and capacitor.What I used are cheapy resistors to begin with, and I am about to connect the 5K parafeed OPT and 6uF 450ACV blocking capcitors.
thank you,
C.Y
