I'd thought about using a solid piece of masonite with forced-air cooling (a muffin fan) mounted on it. I did this several years ago for a McIntosh 240 amp inside an entertainment center and it kept it quite cool. The Westy's a beauty!
I'd like to find one but suppose this is Fate's way of keeping me out of trouble. Besides, the house needs painting.
It's a shame work gets in the way of our hobbies...
