I currently have on the bench an amplifier whose chassis literally rings like a bell.
At power up the tubes really ring also.
I was thinking of using PL9000 to damp the chassis and transformer covers. Has anyone else tried this approach? It's really easy to work with and dirt cheap compared to more "hifi" options.
As for the tubes themselves ringing at startup, I think that is a circuit issue. I can't help but think that tube life will be diminished with that kind of hammer blow every time I turn the amp on.
Any thoughts would be helpful.
The amp is a Yaqin MS-300C
