So Skip,
While your are cooling your heals till you get a packet from Chuck there are some simple things to get the chassis ready.

Those round thingy just above the three rf coil that look like a condenser on a bracket. These are #'s 7,12,and 17 One at a time unscrew the mounting screw. turn it over and cut the ground wire off. Solder a .1mf 630v from the ground wire to the end terminal on the end that is connected the coil. Repeat two more times, those caps are always shorted and kill the B+ to the rf amp tubes.
Measure the resistance from that end terminal to it's associated plate pin of the rf amp tube. Should is a low resistance like 50 ohm or less. If not coil is open. Repeat two more times.
Measure the resistance across the two audio transformers to find any open windings.
That should keep you busy for a while. I think Mrs. Skip owes me a thank you for keeping you out of her hair. [Image: http://philcoradio.com/phorum/images/smi...on_lol.gif]

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!
