6H30 tubes ringing in BAT VK-300SE

I have had this issue in nearly every 6H30 tube I have bought for my BAT VK-300xSE integrated. Whenever I switch inputs, or the unit comes out of warm-up mode, or out of mute, I get a high pitched ping followed by a ringing sound out of the speakers.

I have tried 3 different sets of tubes- two pairs of Electro Harmonix gold pins, and one set of Sovteks. Eventually it gets to the point where if I tap on the chassis of the BAT, I get the high pitched ping/ringing out of the speakers. The last new set of EH's I bought, when I pulled them out of the box brand new, and tapped on the side of them with my finger, bingo- it audibly rings in my hand!

It doesn't seem to affect the sound, but none the less, are there any good sources for QUALITY 6H30 tubes? I am not going to pay $300-$400 for a pair of the "New old Stock" DR tubes. I have bought all of the Sovteks and EH's from Music Direct. Maybe they got a whole batch of bad ones?

Please Help!!!

Karelfd-
I am assuming it is the tubes, because if I tap on them even when they are not in the amp, they ring.

I do already use Herbie's tube dampers.

I have actually asked Victor at BAT about this, and he did not really have an answer at the time, other than for me to send it in to them to take a look at it. I would rather not send it in, as I think it is the tubes and not the unit, which if that is the case would be a waste of time and money.

Thanks for all of the responses. Good information here. Seems like I have confirmation on what I was suspecting- it is a tube issue, but live with it as it does not seem to affect the sound. I was more concerned with getting feedback from other BAT owners that it is NOT a problem with my integrated.

I do very much enjoy the BAT sound. I guess that it is just more of an annoyance than anything else.
