recommendations for tube dampers???

I also apoligize for the brief hijack.Welcome back Z,good to hear,Bob

I have been trying to build my own DIY tube dampers, and im getting a ring of softish urethane to make a good and removable damper.

Chatta,

I'm sure urethane can work, but make sure it's of a formulation that will withstand the temperatures of a hot tube. I received a used preamp once with urethane dampers and they were a sticky mess. No idea how long they'd been in use, but they weren't doing much damping by the time they got to me. I stick with silicone just because I know it's one material that will stand the heat.

Hi Kats, not saying that tubes are never worth it or that SS sounds tube-like, just that to my ear the flaws I often perceived which made much SS a musical compromise, seem to have been proven largely solvable by this point. (And I know one leading long-time manufacturer of both tube and SS amps feels this is the case.) So IMO abiding tube disadvantages isn't imperative to get sound that's not constipated and synthetic sounding.

Has anyone experienced that dampers (Pearl, Silicone rings, Herbies etc) helped extend the life of their tubes? So far I've just placed Silicone rings on my preamp and power tubes. I've noticed no sonic difference with or without them in place the systems I've used my tube amp in. My experience with tube amps are limited though.

I'm just thinking now about using dampers from either Pearl or Herbie's Audio Lab to help with the heat and possibly prolonging the life of the tubes. Thanks
