So got up and thought I'd put some battery juice on it and see what happens. Well nothing! Battery power was up to snuff but no audio. Did some quick troubleshooting to find that I had cut the ground return for the output tube's filament. Fixed that up and it sprang to life.
But one other issue cropped up, I don't I can turn it off. No click. Most farm sets have a dual switch on the back of the volume control. One set of contacts breaks the B battery connection and the other the A battery connection. This way there can be no current drawn when the set is off. I've have had sets from the'20s which just break the A battery supply the thinking is that if there is no filament voltage (A battery) the tubes won't draw any current. This is true but God help your expensive B batteries if you have a leaking plate bypass cap. Doesn't take much over a week or two to drain them down to unusable. But I digress. Disconnect all of it's tentacles 3 on the vc +1 for the loudness tap and 4 on the switch and pop it out. The **** works fine! Clean it up put it back in. So now I'm thinking that the off/on flag is what was causing the problem. I was a little stiff. Cleaned it and a bit of oil and we're back in business.
Still have to mate it with the cabinet/spkr.
This set probably hasn't been played since the 50's or 60's or earlier. I think of it's first owner back in '39. there was a of action going then. The UK and Poland where feeling Hitler's wrath. US economy was gaining some steam but still sluggish. Worlds Fair in NY the place to be if you can afford it.
The farm set was used in locals with no in coming AC electrical power. Kerosene lamps for light after dark fire place for heat. Hand pump your water from a well.
This owner after a day of work just want's to sit down and relax with a pipe and his radio (w/his kero lamp to see the dial). Have a few laughs with Fibber McGee & Molly or try to outsmart the experts on Information Please.
We've come pretty far!!!

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 it!
