Philco 91-121 sensitivity
#15

At +32 v on the cathodes the tube aren't going to conduct much. I've had two model 91's a 91B and a LZX but it was many yrs ago like in the late 80's. Don't remember a local /distant sw position, pretty sure both of mine were bc only models.

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!
