Convection cooling is a wonderful thing. Why some head makers still design upside down puzzles me. I understand the economic reasons behind using the same chassis for both a head and combo, but why not take advantage of allowing things to run cooler? Transformers would dig it too. And the chassis wouldn't have to do most of the heat sinking. Gotta love how Friedman mounts his combo amps with the tubes are sideways. The knob text is upside down when viewing from the front, but that's a compromise I'll take to keep the tubes running cooler. Thoughts???
