Rob, This is a little off topic but I have a couple of 370's also and noticed in the stock configuration that do to the placement in the cabinet of the spkr it's very near the power transformer and induces 60cy hum into the field coil. If you operate the set with the spkr out of the cabinet the hum is gone.
Have you noticed this?
Obtw Great series and will probably be doing to a 70B and a 370 after I gather up so bits and pieces. Both need the initial service and the B needs a front panel.
Tnx Guy's for doping all this stuff 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!
