Does the oscillator have an adjustment?  If so, is this somewhat accessible
without destroying the assembly?  Are there pictures of the oscillator
assembly?

I dug in deep and there is an adjustment. Thats the great news. The bad
news was never able to put the oven back together.
It was a mess. The insulation stuff deteriorated. (Might mean over heated
oven)
The various wires going to the oscillator are wrapped about 4 times around
the oven. I am sure the reason is to stop temperature variations but seems
painful.
