Newbee,
The ringing I hear is low level. Go back to my intial post and you'll see that I only heard this ringing when I "changed my CDs and was close to the amp". Certainly, I'll switch some tubes out and see it that solves the problem, but if it's just "low level ringing" then perhaps dampers might be the way to go. Basically at this point, I'm interested in what results people have had with dampers.
