Model 89 Cathedral
#20

Thanks for the links.

The winding and decaying plastic came off with a little help from the heat gun. I carefully made a diagram, noted the coil turns and direction, but somehow completely forgot to see which pin goes to the top or bottom Icon_mad I think lug 1 (from the bottom clockwise) goes to the bottom, and lug 2 to the top. Can anyone confirm?

The windings underneath seem to be in decent enough shape, but there is a bit of green corrosion in some places. I can't tell whether it's from the messed up coil, or the intact primary itself. Resistance matches the schematic, and looks like well over 100 turns. I'm going to clean the green stuff with rubbing alcohol and lacquer it unless anyone says not to. I can post a pic if it would help.

A couple resistor questions. There is a 51k resistor in the avc circuitry, the closest I had was 57k. That's a bit over 10% off, is that acceptable?
Also, the volume pot is listed in all schematics as 350k. Mine reads 230k, which I think is a rather substantial difference. I bought the closest pot I could find, that I'd rather not use, at 250k. Any thoughts?


Thanks!

Will
