Hello all,
I've got an Ampeg 2x12 Rocket Reverb. Recently i've had some
troubles...most have been fixed by buying new tubes, however i've still
one lasting probelm. After...5 or 10 minutes of play my power starts
to fluxuate. The volume, and gain will seem to dip...sometimes very
drastically other times not as much. This also occurs consistantly
when i turn the master volume past 4 or 5. Could something be getting
too hot? I am 20 years old and am working on my EET degree but
unfortunatly we dont cover much about tube audio. Feel free to talk as
"techy" as you wish to me, but i am still new to tube amps but very
willing to learn..Thanks for all the help

What exact model is it, and if early, did you replace the Rectifier?
