I will replace the 220k with some 100k.
As for the zener diode string from what I have read this will be in series with the center tap and not the b+ ?
I also have a problem with the negative bias supply the selenium stack I replaced with a silicon diode I was to inexperienced at the time to account for the voltage or less of a voltage drop and now it will only let me adjust down to -32 which gives me about 18ma on each of the output tubes. Would it be OK to put a zener in the bias supply to shed some volts?
Thanks for all the help!
