Tnx Mike,
That solves a couple of mysteries. [Image: http://philcoradio.com/phorum/images/smi...n_clap.gif]
Why it uses a large oscillator tube, What a rf signal is doing in the BOL, and maybe why I can't get it to tune below about 630kc.
I put a jumper across that pickup winding and it shifted the lo up about so maybe with the BOL plugged in there is some resistive (lamp) and (cable) capacitive effect that will correct the alignment. One can hope.

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!
