Best tube dampers that you have used


I currently have a Thor Audio monoblocks TP-150, 8  EL-34's Sovtek tubes for each amp.
Was wondering in anyone's experience will tube dampers improve the sound quality.
Am hesitant to proceed as I have read that  tube dampers can melt from the heat of the tubes and sometimes
cause smoke. Any thoughts would be appreciated.

I use the Pearl Tube Coolers with a bit of a modification.  I solder a wire to them which I run to chassis ground.  Not only do they drop tube crown temp 10 to 15 degrees they eliminate any RF interference via the grounding and provide damping.
