Wtd: Service man/schematic TM-631A
 

I need to repair my Kenwood TM-631A and would like at least a schematic
diagram. The prices of service manuals from those who regularly sell them
are a bit steep.

I would like to get a photocopy or borrow one long enough to make a copy.
An original would be best of course.

I believe the TM-731A is very similar, as is the TM-741A etc.

The problem is in the receive audio section and should be simple to
troubleshoot but I don't know the setup.

Any help would be appreciated.

Sincerely, Bob K6DDX
