Hello,
I would be happy to purchase a board or exchange with you but I am stumped!
I am more than qualified in electronics repair as a professional rf guy and a ham but my r-83 just all of a sudden lost its volume while all power supply lights are lit and the main amp overloads are not as normal.
It sounds like I am only getting pre-amp output as the volume control has no effect on the output and no bass response whatsoever?
If you can help or guide me with the proper replacement parts I would be happy to purchase them.
All appears well but still no volume.
My Thanks!
Rich
