So what happens if you select the appropriate DC range for your meter and measure the DC voltage from pin1 or 4 (either one of the fat ones) on the #80 tube + lead and connect the - lead to the chassis? If all is well should see about 325vdc there.
In order to have an AC volt present at the + leg of the filter caps your rectifier tube would have to be shorted. Does your 80 look angry?? Are there sparks flying around inside it??

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!
