48-472-122 FM issue
#6

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.
