Hello all, searching the posts here yielded no results that I wanted to jump on right away, aside from just retubing.
I'll start with my problem...I have a DR Trem-O-Verb from August of '94 (serial 4279) and I'm experiencing very very low output on the Orange channel. Red seems fine, loud and full, even with Orange cloned to it, but Orange is a different story. I can crank the volume and gain to max and I can have a conversation with you at normal talking levels over the output. Gain and volume pots are indeed working, as rolling either off fades to no sound at all.
It does have Mesa branded Sovtek 5UG4 rectifier tubes, Groove Tubes (sovtek) 6L6's in the power slots and a mix of Mesa and Groove Tubes 12A7X's in the preamp.
I have not started swapping tubes as of yet, as I'm not entirely sure if that will remedy my problem.
Speaking with Mesa I was informed no one tube will have any effect on one channel specifically (at least none of the preamp tubes), and they advised boxing the head up and sending to them (roughly $200 in shipping round trip).
I have tried switching between bold and spongy, double- and triple-checking I'm not being fooled by FX loop, and switching between rectifiers, all to no avail. Just making sure I'm not missing something before I order tubes or have it tech'd. I read somewhere that a faulty rectifier tube could be to blame, but I haven't tried this yet, just looking for maybe a point in the right direction before I start throwing cash at it.
Thanks.
