Hi Tom,
As Rod pointed out the avc and the osc are two different circuits and don't really have much to do with each other. Like adding antifreeze when the gas tank is empty and thinking why won't it start.
>Could that lack of negative voltage shut the oscillator down?
Yes. The negative voltage is developed when the oscillator is oscillating. Just adding a negative voltage there isn't going the make it work.
Did you disconnect the 2ndary connections from #28 and add the choke?? At minimum I would think that it should get the pb working.

When my pals were reading comic books
I was down in the basement in my dad's
workshop. Perusing his Sam's Photofoacts
Vol 1-50 admiring the old set and trying to
figure out what all those squiggly meant.

Now I think I've got!
