All,
My solution is two 4.5-inch, 48-volt dc muffin fans sitting on half-inch
tall rubber feet covering the top exhaust vent on amp. They are running on a
19-volt supply at a slow but effective cooling speed and are very quiet
(drawing air upward). During normal CW rag chewing the main fans do not come
on -- a vast improvement for a few bucks. When you go portable, just leave
'em home.
