I never understood this problem. If a room is hot enough to be uncomfortable I guess a tube amp could be a focus of your misery. I own 8 output tube amps in two systems running class A and if you a close they are very hot. It seems as though you need better overall temperature regulation for your room. I have been fortunate to have very quiet central air and a sub grade cool basement.
small room... tube amp... summer
for those in relatively small rooms, how do you deal with the heat from your tube amp during summer? can i point a fan at it? any suggestions? it's really heating up my room and there's no AC in here! do i just have to bear with it or are there any practical solutions?
