tube dampers anyone

pforeman · 15th December 2010, 11:03 PM

I've just come from the hardware store and bought some cheap o rings. They come in all sizes and could therefore fit any tube
They're made from Neoprene.
Looking up neoprene on the internet, it looks like their melting point is way high
I've never used them.
Only have them on the 12at7 tube so far (simple se)
Do you use them
Do you use them on all tubes (even 5AR4)
I would think that with all the bass in my room, those tubes are jiggled by the sound a lot, and tube life should be better with dampers?
Dick Olsher ?(stereophile) a long time ago said that they transformed his average tubes to exalted status. This was way before these fancy tube dampers I see advertised now.
Thanks
Paul

I used some I had on hand (from the auto parts store) to dampen microphonics in a pentode front end of a guitar amp.

I was surprised at how well they worked.
