Re: The 6H30 tubes run WAY hotter than 6922s

The Pearl Tube Coolers draw heat out of the glass and into hollow vertical metal columns formed by pleated fins. The hollow fins in turn are cooled by the convection effect of hot air rising up the pleated fin column and out the top into atmosphere. The smokestack design of the fins creates the convection, which will not be produced by glass, glass-metal, or glass-metal-air contact alone. This convection effect, together with improved heat-transfer owing to the large surface area and thinness of the pleated metal fins, WILL lower tube glass surface temperature as long as the temperature of the surrounding air medium in the chassis is less than the surface temperature of the glass. This is true whether the chassis cover is on or off, but of course, cooling is improved with the cover removed. There is no absolute limit to heat dissipation of the chassis. And even a 50 or 100 degree reduction in tube glass temperature will extend tube life.

Unlike some audio accessories, the Coolers are based on good science.
