Hello Rogue Owners. The goal of this thread is to let Rogue owners discuss the tubes they have tried in their amps/preams and discuss other tweeks that have been implemented with success. It would also be nice if you'd post your system components to help us compare notes.
It's probably a ground loop hum. I had something like that on the same amp (as well as many others) and a cheater plug (3 prong into 2 adapter on the AC cord) solved the issue. Try the amp first, then the preamp and so on.
