I had this posted in Audio-Karma under Tube Gear - but this is probably the right place (cosidering I got zero responses)
This is my latest project (can't seem to help myself).
This is a Grundig Tube table top radio with turntable (top lid opens to reveal turntable). The cosmetics are in really nice shape (9/10).
My problem is with the tuner dial assembly. These radio's had one tuner dial to operate both bands. Band selection buttons moved the tuner section to utilize one of the two tuner's. I've read that it is like a clutch mechanism. I've attached some pictures.
Turning the tuner dial only turns the flywheel and neither of the tuners. Band buttons move the tuner assembly so I think that is working fine.
There is a rubber section that obviously needs replacing.
Does anyone have any experience repairing these tuner's? I can't find any schematics or parts list anywhere.
Thanks
