For those who might have some insight on this problem,
Nostalgiaair Schematic: http://www.nostalgiaair.org/pagesbymodel...013637.pdf

Audiophool Schematic (better quality): http://www.audiophool.com/Philco.html

R203 is the Trebel Control and R207 is the Base Control.

Unfortunately I don't have any thoughts on what could be wrong.  If it were me, and it has been, I would double check the wiring ... I've driven myself crazy by mis-wiring something.

Yeah, I'll take another look. When I needlessly added some ground wiring I did match up the schematic some, but it's worth a deeper look. Thanks.
