Is this a good idea or bad idea?

Hi all,

This thought keeps popping up in my head every now and then. What are some of your thoughts on it?

I am in the process of a complete resto. on a 1960 console stereo/television. I have done the recap and am now working on a complete resistor changeout too. Then I will install a completely new set of NOS tubes.

While I have been deep inside the bowels of this set woking on adjustments, I have been amazed at the heat that is produced by all of the tubes and components. I wonder how it affects the caps and resistors and tubes over the long run?

Would it be beneficial to install something like a 4 or 5 inch tech. fan (same style like on the back of computers) inside of this box or mounted on the back cover to keep some cooler air pulled in and circulating? Should it be aimed right at the chassis to help cool the tubes to maybe prolong their lives or would this potentially harm the tubes by cooling things that are suposed to get hot?

The temp in this cabinet gets at least 100 degrees or so when completely warmed up.

Appreciate any thoughts on this

Personally I don't think you need to change out all the tubes--I have found that most old tubes still have plenty of life. The only thing I generally completely replace in old sets are paper capacitors. I change electrolytics only if they appear to be bad.

The real damage from heat is when the heat from tubes overheats and shortens the life of resistors and capacitors. Is this a b/w or color set? Most console b/w sets I've seen don't seem to get excessively hot, as they have fewer tubes that color sets, which always seem to be very hot in the cabinet.
