The tuning motor does work well, by the way, though the capacitor tends to start to sizzle after much continuous use.

Hello again, Thomas. Hoping you're still open to figuring out if the tuning motor and bits from your possibly RCA 911K chassis are the right one. I know that the mechanism from the 811K is cosiderably different. It appears to use switch contacts instead of the brass wheel with the insulating strip to set up the station presets. I sent an email so this posting may be redundant. If you're able to email me a photograph of the tuning motor and gears I'd be able to tell if it's the correct one.
Thanks Thomas
Al Wiebe
