Hello All,

I have a Diezel herbert and love it. My issue is that my 2nd and 3rd channel seem to some times go almost "muted". The 1st channel works fine, but the 2nd and 3rd channel will produce very low volume with no distortion. The only thing that fixes it is to let it sit. It seems to happen more often when I switch the channel more often.

It is becoming an issues since I have some shows coming up and their is no predictability as to when it happens.

I can not find any diagrams or wireing diagrams to aid my amp tech.

Any help is appreciated.

Thanks in advance,
Luke

Hello Luke,

get yourself a new set of preamp tubes. How old are your power tubes?

I've got the Diezel selected tube sets available.

Best regards,

Enzo Ferrari's assistant

No idea I got the amp used in march 2011. Visually the power section looks and sounds good. Amazon beat you to the,v1 slot. Shoot me a pm on the,price of the remaining ones.
