If you have zero volts on filament pin 3 of V1 then it ain't lighting!

You should have 6.3 V AC between pins 3 and 4 of V1.

If V1 filament is not lit, then it will draw no B+ current and your voltage on pin 1 plate of V2a mixer will be too high, as you mentioned above, because both are after the same B+ load resistor.

The wife was a bed hog last night, so I woke up at about 4 AM and decided that I was up. Here's where I'm at.

I cleaned the snot out of the pins on V1 and now have correct voltage on pin 3. As to whether it was lighting before, I was fairly certain, but who knows....it was early this morning....so I just went ahead and cleaned the pins and the voltage was there.

The voltage on pin 1 of V2 is still unchanged.

Going to toss this set in the van and have Tom (Electronic M) take a peek, as long as we'll be seeing each other at ETF. I might bring the other tough dog 7" for my replica pre-war too....spread the fun around a little, and maybe I'll learn something in the process
