>I know these values are a little off
A couple of thoughts. Could have a replacement power transformer that is a bit lower in output voltage, weak 5Y3, or something is loading the power supply down. In any event the hv voltage are still are within 10% of where they should and that's good enough to do some troubleshooting.
I wouldn't condemn any of the tubes so far as for the most part a weak tube will still work short of the heater being burned out.

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.
Circa 1966
Now I think I've got it!
