You may be able to get some ideas but there are significant differences
between water and vapor phase cooling. You need to be absolutely sure
that the water does not boil with water cooling. The issue will be to
assure sufficient water flow and radiator capacity.

The Alpha 70V used a 3CV1500A7 (c. 1990) and worked very well.
Some info on that is in the manual:

Some good images of the amp, inside and out, including close-ups of the cooling tubing connection to the tube etc.

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