I took the Model H speaker apart today, and remeasured everything. One of the wires going to the voice coil had badly broken insulation in several places, so I heated it a bit to straighten it out, then put some shrink wrap on and pushed the shrink wrap as close to the windings as I could get it. Seems to be OK, now. It measures right at 3.3K.
The output transformer is open on one side, so that's more bad news for this badly used set. I'm guessing the primary because the side with resistance measures under 200 ohms. I wonder if I might be able to open the bell housing and repair the break? I've never done it before, but have little to lose there. Any advice before I try it?
