Hello,
Before we go any further is the (balance) knob at the 12:00 position?
You stated that when you swapped the cables it was “fixed”. It is kind of confusing. The only other thing I can think is when you swapped the tubes you did not redo the bias of each tube. Rogue has been known to have a bias setting for each individual tube. Please do this first. They even give you the little inset screw driver so you don’t arc anything. Once you bias each tube to factor specs redo your test. Positive to positive and negative to negative. If it is still unbalanced try the opposite. I have a feeling in swapping things around certain things were not done. These reasons may be why it worked on another system but not the Rogue. I hope one of these works so you can get back to listening.
