First Resto - Philco 60B
#12

It would seem that your 78 is a bit weak as it's not drawing enough current to cause a voltage drop across it's screen resistor. This will effect the amount of plate current it draws. That could be the reason for the high reading on the 78.

As for the generator if you have a local station at 920kc you can use it's carrier beat against the signal from the generator as it's the 2nd harmonic of 460kc.

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!
