Joe, your meter should give a negative kick when applied to the grid of the oscillator, pin 9. Set to volts. No kick, no oscillation. That should narrow the search down to related components. The triode anode voltage is far too high, indicating no oscillation. It should be around half that voltage. Judging from the 150V on pin 6, your HT level is down about 20 volts too. That won't help the local oscillator, though it isn't likely to be the cause of the problem unless your valve is low in emission.
