Ever look at a "combo" guitar amp? For example, a Fender Twin Reverb (I’ve owned and abused a couple of these) has 4 6L6 power tubes and 6 preamp tubes, all mounted upside down venting heat into the amp (although they’re uncovered...still...), and if you tilt it back it’s worse heat wise...but my amps never failed to work tirelessly. Kinda makes hifi stuff look weirdly delicate and wimpy...vibration? The amp is also in the same space as 2 12" speakers and still manages to work...all night...
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?
