The Alpha 70V used a 3CV1500A7 (c. 1990) and worked very well.

Some info on that is in the manual:  https://www.alpharfsystems.com/wp-content/uploads/2016/05/70V_Manual.pdf

Some good images of the amp, inside and out, including close-ups of the cooling tubing connection to the tube etc. can be found here:  https://www.google.com/search?safe=off&rlz=1C1GCEU_enUS901US901&sxsrf=ALeKk00Q2VBQ2AirnWhorc7Sy_RknC9tLw:1614270777508&source=univ&tbm=isch&q=alpha+70v+pictures&sa=X&ved=2ahUKEwiDxY6iu4XvAhW4HDQIHcl2DCIQ7Al6BAgEEBA&biw=1920&bih=1089#imgrc=sPrzcLglsbhLFM

If I were to homebrew something, I'd likely copy what they did.   It was compact, efficient and very quiet.

Anyone using the water cooled version of 3cx1500A7.
How'd you do it?
