Best temperature for optimum tube performance

Report back here- where fifty people who have never bothered to compare anything their whole life will rip you apart for your expectation bias and sloppy experimental technique.

 
MC, why can't you just make a suggestion without adding in a comment of how stupid or ignorant or insensate other people are? You have experience and knowledge and you are willing share it. Why must you snark? Something not going right for you? 

A new band, Snarky MC?

Just kidding loved the use of “snark”

I enjoy MC posts and his view.

Why fan at the front and at the back where more heat would be injected out from the cabinet?
Output tubes and even signal ones produce considerable amount of heat stressing close by components like caps. If you cannot move equipment in open air then what you did is fine but it is difficult to tell if the cooling is uniform.
All tube spec sheets provide data at a specified ambient temperature. So if within that temperature they should work as intended.

Check it out: people taking this seriously. People who most of them never even notice a difference as their components warm up. People who will argue and deny there even IS any difference as a component warms up. But here they are imagining all kinds of crazy theories about how to optimize this imaginary tube temperature performance envelope.   

Sentence first, verdict afterward! Lewis Carroll knows you guys all too well. 

A snark, a snark! My Kingdom for a snark!

The tubes don’t mind the heat too much. The passive components like electrolytic capacitors would prefer it a little cooler. Although if you’ve been doing it for 40 years in that cabinet, with a fan, you’re probably fine. Just don't tell them that if you ever make a warranty claim.
