There are all manner of inexpensive and very lower power consumption fans and cooling systems available for computers. Hell, if you have central air conditioning you could even route a hose of sorts to blow into the set.
Reason I'm stuck on the cooling (and stuck on stupid as well) is to extend the hours a day you could run the set and reduce any impact on ultimate longevity.
I see operating older electronics like cars, no use is as detrimental as abuse...and there's an "in between" that actually lengthens the life and improves operation.

I agree the use of a fan is best for the life of these old sets. I have fans on all of mine since the parts can be hard to find for these old sets and I have read on line the guys that use the tube amps use fans and it makes the tubes last longer.
