rig sounds like thunder!!??

[tramp]

Have been playing recently with the band and have found that the triaxis & 20/20 is making thunder like noises mostly on ld 2 +3 sometimes very pronouced other times not....then the sound usually dies away..but comes back when switching between channels

would I attribute that the valves or the 20/20 or triaxis!??

Idea's anyone experienced the same thing??

Cheers

Sounds like the triaxis is the problem. You should probably replace all of them just to be safe. The 20/20 is only supposed to last a year on the EL84's and the 12AX7's usually only get replaced if you are experiencing odd noises. I prefer to replace all of my power tubes tubes once a year and once every two years for the preamps.
