Hi people, I'm the happy new owner of a Mark V head, it's awesome!
I've had, however, the following issues:
1. Channel two sounds lifeless. I have to crank the gain to max to get a decent tone in it. Mark I mode sounds like only bass frequencies come through. Channels 1 and 3 sound wonderful, though.
2. Using my Decimator GString on channel 3 leads to a high-pitched squeal. When I've had only my Memory Boy on the FX loop everything was fine.
So, searching older threads, it seems I might have two busted preamp tubes - V2 and V6, right? I don't have any spares to test with, but I have another amp with working Sovtek 12AX7s. Could I take these and put them on the Mark to test?
Thanks!
