Merkaba,

Caig Products De-Oxit and Pro Gold will probably fix that noisy pot right up...worked wonders on an old Sansui I have as well as a Nikko for the neighbor...

It will involve partially dissasembling the receiver to gain access to the pots...spray it in, work it back and forth through the entire revolution of the pot, let it dry, reassemble and it should sound much better...

Works on switches too...

YMMV,
