Hi Jake
You kinda lost me. Are you saying that without the rectifier tube in place measuring the AC voltage from the 80's socket skinny pins you got 400vac? If you measure the AC voltage across the two fat pins what do you get?
Or another way is to measure the resistance from the wire that goes to #70 to the transformer against each of the skinny pins of the 80 socket. Should show several hundred ohms and be fair close in resistance like 100 ohms or so.

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!
