I have the "white" version of the 6800. Appears to receive OK,
however on shortwave (only) it doesn't tune, and the digital counter
won't increment/decrement. Mediumwave is fine. The dial cord and
mechanical assemblies appear to function OK, and all contract switches
have been cleaned. There are some sealed metal shielding areas that
look painful to access, and reluctant to go that far if not needed.
The service manual isn't a lot of help.

Does anyone have experience of this particular problem with this
receiver?


Thanks.
