Gene,
Let's swap information then.
Here's what I've found so far.
1. The speaker itself is looking good.
But when checking the speaker plug with the meter, I have the resistance between internal two pins at 900 Ohms (should be 1K I think), and this is the field coil.
However the outer two pins (I think it is the primary of the audio Xfmr) is open. I think it is busted.
What do you have there?
2. When I removed the acoustic adapter, there is that rod that hoes through the speaker, and there is some grooved bracket hanging off of it, and there is some loose tape and insulator wrapped around it. I think it is the support for that nut that is the stop for the adapter, but not sure. It is loose, so I wonder what, if anything, should be done about it.
3. Since the Output transformer is likely kaputt, I think there maybe a problem wit the 6F6G tube, but that's minor.
I will need the transformer winding data, I am going to try to match one of those Hammond jobs - did it to Philco 20 (same problem).
4. The big multi-tap resistor is a bit off, but I have to figure what they mean by the "M" in their value markings of the resistors in the manual.
5. The mech. assembly (cogwheels) rotating the runing cap is frozen. Guess that contributed to the belt going kaputt.
The other belt (manual shaft) is OK, but nothing moves. Perhaps some WD40 or White grease will unfreeze it.
PS. The cabinet indeed looks OK. No one tried to restore it, and though it has its share of scuffs, I think it may be fixed by a skilled person (probably someone other than myself )
