Hi Terry,

Here's what I got: Touching pin 1 of the 12AU6 did nothing. Touching a cap to pin five was as you stated-just like touching pin 8 of the 14F8. I measured the voltages at the 12AU6. The only ones that were correct were the filament voltages. The others were 0 or negative. 

Any ideas were to look?
In the meantime I'm going to check more voltages.

Thanks for your help.

You can probably save it using coils on the wire leads. Try unwinding a tad off each end of the rf coil.RodB — 09:47 PM
