Went back and checked things again, with the power switch in high these were the voltages:
80 tube 1-4 was 4.5VAC, 26 plates were 46-47 V, 71 plates were 107 V.
Put the switch in low and 80 went to 5.5 VAC, 26 plates went to 84-87 V, 71A plates jumped to 214. Brought the variac down to 100 V, switch still in low and got 4.6 VAC on the 80, 26 plates were 71-72 v, and the 71A plates dropped to 136 V. Redid the resistors and made sure they were close, changed filter cap 5, .01uF becouse I wasndt getting a voltage drop across it or at resistor point 5. Now I have 24V drop. Concerned about the plate voltage on the 71A's. being to high. Whats next
Thanks,
George
