Heat

Just remember your removing the heat, not cooling the unit. By cooling the "WAY" it transfers heat, (the heat sink fins) it PULLS the heat out of the enclosure quicker, just like MC said.. By using internal fans and conduction. One is drawing heat out and the other is replacing the air inside the case.. Neither will work when the ambient is HIGH. It can actually work the other way with the heat sinks. They exchange heat, which ever is the lower, outside or inside..

A block of ICE. Fix you right up.. Maybe set the amp on the ice, not the ice on the amp.. :-)

Must be an ugly one to hide in the attic? ay?  I had a girlfriend like that.. I just used a bag when I got drunk, then double bag when I'd sober up..

Boy could she..... Dance.. :-)

oldhvymec, yeah, the difference between a dog and a fox is about two beers.

If you have ever tried to cool a hot food liquid in a spoon (in order to taste it) inhaling the steam/heat is much more effective/faster than blowing on it.

Because of this in the few instances where I've used fans to cool tube gear I implemented the fans to draw heat away from the unit (VS blowing air on the unit).

Motron looks like AC Infinity with less features for more money.

I use two computer fans underneath 845 SET amp, tremendous current and heat from these transmitter tubes. Don't bother with my other tube amps and pre.
