Be very careful and diligent with precious tubes...isolate them from harsh vibration and nurture them like sweet little gentle babies. Be nice to them. Except for the tubes in the 147 guitar and bass amps I've dragged all over the world since 1967.
Ringing Sound In Tube Gear
I recently have begun noticing a feint "ringing" sound while playing my Onix H34 integrated. It comes and goes and I'm sure it's not my ears. Could this be a problem with the output tubes? Any advice would be helpful. Thanks
