Howdy,
I started working on my 920... found some bad Potentiometers. I've been searching for replacements but have found nothing so far. Here's what I found in the TT:
R14 300ohm clarostat pot (1 11/16" in diameter and wire wound)
R13 40ohm pot also wire wound.
The larger one, R14, was really fried and very smelly.. it took a lot of heat at some point.. and no.. it wasn't me doing the fry job. (grin)
The 40 ohm was missing it's cover and would sometimes work but most of the time not. It had been subjected to a lot of moisture.
I just hope that whatever caused this is gone.. and that this isn't too expensive to fix.
Schematic for the 920 is here:

Anyone knows of a source for these high wattage Pots I'd appreciate the info.
