Best temperature for optimum tube performance
Is there an optimum temperature range in which tubes perform best?
I've been running tube amps/preamps for over 40 years and have always placed a small, quiet fan in front of them to prevent excessive heat build-up (a modified, two-door antique silver cabinet is where they reside).
I'm aware that electrical resistance increases in proportion to increasing temperature, but am I somehow decreasing the optimum performance of my tube components with this strategy?

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. G |
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!

It takes very little air flow to cool a chassis significantly. I've been doing it since the 70's. A couple of 12v 60mm PC cooler fans running on 3.5v are completely silent and cool the internal chassis from 50°C to 30°C on my tweeter PrimaLuna PL-5. Ditto a 100mm on midrange VTA M-125s.
