Not tired anymore (much) and started playing with cathode resistors. I have a single 5000 ohm wirewound resistor hooking all the cathodes together, bypassed by a 1000 uF cap, and get these results:

Plate= 440
Screen= 340
Grid= -25.5
Cathode= 15

What voltage should I be shooting for on the cathode resistor seeing as I've reached the maximum the bias power supply can put out?
