So I'm aware that tubes go bad after so many hours. I've had Mullard M8100 and Ulyanovsk 6S19P-V tubes in my DV332 amp hooked up to my AKG K701 for about a year now. They still sound pretty good though lately I've noticed a hissing sound at higher volumes. If I turn the amp more than about 40% I hear a hissing sound which gets louder as I turn the volume knob.
Definitely isn't a ground loop, I have a Xitel Ground Loop Eliminator and I tested with a 3-to-2.
My question is, one, do you think the tubes being old is causing this? And secondly, which set of tubes would it be, the driver tubes (Mullard) or power tubes (Ulyanovsk)? Thanks... I'd rather not buy two new pairs of tubes if just one pair needs to go. Thanks.
