>1. No numbers on the power supply .. except 305 in a circle..
Was hoping that it had a model # for that power supply.
>I have NO RFC4 .. That point goes directly to the coil of a Relay .. I measured about 14.4 K
I suspect that's why you got so much negative voltage. That negative voltage is used to grid
block key an external VFO. The rca jack on the back marked vfo is not the signal it's for keying.
Also it goes up to the mic jack so may have some sort of ptt circuit.
>So looks like I do not have the right schematics for this set..
Or maybe it has the wrong p/s. Don't know.

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!
