Just for fun, I'd like to fix my old toaster oven. It was not very
old and in very fine condition except for a burned out thermostat.

Its a Magic Chef model ctb650m, and the thermostat is a mechanical
type, with the following written on it:

Keensound 125V 12A KS198 1300

I have written to the MagicChef address on the user manual but so far
received no reply. I think they may be out of the business. I wonder
if there are any suggestions on how to obtain a replacement or
equivalent thermostat. Even a similar one that I could rig in, even
if temperatures were off a bit, would be fine.

Thanks, Guy
