Project Link: Saving the Kenwood TR-751/TR-851
Many owners of the Kenwood TR-751/TR-851 have experienced the problem with the
low quality
potentiometers for the Vol/Sql and RIT/RF-gain.
The even
bigger problem is finding a replacement, especially in Europe.
If you klick on the link above you will find a description of how I solved the
problem by using standard
10k potentiometers and a small peace of
experimental board.
