I have a hughes and kettner tube 50 head, I bought it used and the guy I bought it from replaced the tubes 5 years ago.
I replaced the tubes and rebiased it, but there was one preamp tube that was stil reading 80%. Should I leave it there? And would it have a big affect on my tone if do replace it?
The tubes I put in are svetlana's in poweramp and mesa's in the pre-amp
