Low voltage on Heathkit IG 42 signal generator

The heathkit manual calls for 65volts on pins 1and 7 of the 6AF4 oscillator circuit. I measure 23 volts. I have checked voltage on the 10k ohm dropping resister I read 107 volts on power supply side and 23 volts on 6AV4 pin 1 and 7 side. What am I missing?

Hello Larry,
If the 10K (anode)  and 100K (grid) resistors are OK,probably the tube is gassy.What happens if you desolder the feedback capacitor (0.003 ) from the anode ?In this case the oscillation stops.
