Sorry I was unclear. I didn't mean all the tubes like Andy said, but the power amp tubes. If you've been playing the amp constantly for two years on the same set, more than likely your fix is there.

the amp sounds muddy only on the overdriven channel.
Ive been playing for 2 years on the same set and this is my first
tube amp so I dont know much about it. Iwe been thinking of
replacing all the pre-amp tubes or give it to a licenced repair guy
here in Croatia to look at it.
Any suggestions?

As I said if it is only one channel then try swapping out the valves for that channel. Do it one at a time and you should find the problem valve. Again there is no need to swap out all valves - just find the faulty one and replace it...

Good luck! :)

I'de give the amp a whole new set of tubes all around, rebias. Mullard Reissue ax7's in the Dirty and PI slots and take off all those aluminum tube shields. Your mud will go away.

If it helps OP, plenty of preamp tubes I have used do not glow, it's normal. From memory most of the russian new sensor tubes are like that, you just can't see the filament glowing like some other tubes.
