Here are the 6DR7 resistance readings.
1: 406 ohms (measured from 275V B+ source)
2: 1.97 megohms
3: 1.97 megohms
4: .1 ohm
5: zero
6: 1.68 megohms (measured from 275V B+ source)
7: 67.3 K ohms
8: 51 K ohms
9: 217 ohms
The resistance on 6, 8 and 9 varies with control settings.
The R63 thermistor is behind the yoke. I shorted it out with a jumper and tried the set. No change in height.
