MC25 Rebias?

[memberzonly]

Have any of you done a power tube replacement & bias? I didn't see a bias pot when I removed the chassis. Is there a bias pot? If so, where is it located?

Mine currently has 6L6GC's in there and I want to try 6V6's. Per Rick, it's just a swap to JJ's and a rebias to 25ma. Was hoping to NOT have to replace resistors.......

Thanks.

There is a tiny bias pot on a board at one end of the chassis. Mystery solved.
