Dear fellow cult-of-the-cosmic-orange-dot members,
Would it be possible to surround the tube with a finned heat sink
similar to those used on some transistors? What about ducting that
discharges by the tubes or even surrounds the tubes? Having never
seen the inside of this amp, I may be simply blowing hot air. (ouch)

Hi Gary,
The original post was in regards to an amplifier which uses a pair
(maybe 4) 572B triodes. These are glass envelope tubes. While it may
be possible to precool the air using a chilled water system, there
would still be a need for a fan to blow the air across the tube
envelopes. Perhaps the air flow rate could be reduced and the fan
could be quieter using cooler air.
There are water cooled tubes and conduction cooled tubes, which
could reasonably incorporate a liquid heat transfer media. In the
case of glass envelope tubes I really see no reasonable way that
water cooling could be applied.
