Hello out there. I am new here and attempting to repair a Willsenton R8 that has red plated several KT-88's in the V3 position. I think I have tracked down the problem to the bias pot. It is O/C on one leg.

Has anyone found a decent replacement? Or am I stuck trying to get the Chinese manufacturer to send me the same weak parts?

I have read the excellent mod to the bias board which will be implimented, if I find replacements for the pots.

Cheers

Bob
