Hi

Somehow Channel 1 stopped working :(
It is audible a tiny bit, when i max out the master volume

Could that be tube related?
I doubt it, as ch2 and 3 work :cry: :cry:
 
How old is the amp?
Is there absolutely NOTHING coming out of Channel one?
But the rest of the amp is solid - no noise - no intermittance - no crackling?

History of the amp - bought used/new? Signal chain?

Lets have it.
Lets see what we can do.
Unkle Mo
 
I replaced V1.

There is some hum in ch1, and when i crank the volume, there is a guitar signal too.
Amp is from 2007, bought it in 2008.

Signal chain is Guitar straight into the amp and into cab.

Hey man try replacing all of the pre amp tubes, if you never have.
These parts wear out and your whole amp could probably benefit from it as well!

Always good advice for sure.

But what's odd here is that the signal is dead on Ch.1 but seemingly - as per the OPs post - works on the other channels without issue. That means V1 is still porting the signal through to the other channels and their related preamp stack, over to the PI, then out to the PTs. Granted yes, a fresh bottle replacement is definitely recommended for an amp of this age/stage, but I'm perplexed as to how other channels can work yet Ch.1 isn't. I'm thinking it's a shot pot in the signal of Ch.1. Pot = Potentiometer, if the OP needs clarification. But this may need to be benched by a tech...to be safe; but also thorough.

If you're not qualified to go through the amp. Get someone who actually knows for your safety.
It could be that one of the resistors for that channel could be faulty. Like I said I'm just going by what we went through when trying to diagnose a problem with my amp. :thumbsup:
 
If your in Germany...,
I would ask poppa diezel if he would look it over.
Can’t get better then the god father to check it out.
Pops always stands behind his babies. He’s helped me out in the past. :rock:
