stereo 90 Rogue amp hum noise

If that is the case, sounds like a ground loop to me. Look through threads here and elsewhere for potential fixes.

And/or give Rogue a call.

noise stays at same level---all tubes are new actually and test perfect

And does the hum remain at the same level regardless of where the volume control is on the dial?

And does this noise remain when nothing else is plugged in? Only the Rogue into the speakers with no RCAs attached to the amp (best to disconnect RCAs at the amp so they don't act like antennas).

Did this noise just begin? Any changes in your system or set-up?

Is it coming from both channels?

(you did say speakers but just checking)

Is it possibly a bad tube?

good luck
