Mighty Monarch of The Air

Um.. just to reiterate what was suggested back in post# 62, the plate load resistor of the
V.oscillator is a very common failure point and should be double checked if you haven't already done so. Now that we got the schematic to look at, that would be R66, 470K (half a megohm +/- 10% or so).

And does the V.size control (R4) measure correctly at 2.5 meg or so?

How about the voltage at the bottom of R4? Since it's supplied from B boost, it should probably be somewhere around 400-450 V.
