Stan,
A company named Bernard who makes mig welding guns makes a table top cooler
for water cooled mig guns. It has a self contained tank, pump, fan, and
radiator. You might look for one of these as they do show up on the used
market. New, I'm not sure the cost, but it's probably several hundred
dollars. You could also make one of these with off the shelf components.
They used something like a good sized heater core from a car for the
radiator. The way it works is the pump puts water from the tank to the input
line. The hot water coming out goes through the radiator where it's fan
cooled back to the tank. The pump picks it up and the process starts over.

Subject: [Amps] Water cooled amp question
Hello gang.
I have a chance to buy a water cooled amplifier using a single 3CW5000A7
Eimac tube. I am told by Eimac that this tube is electrically the same as
the popular 3CX3000A7. Here is my problem....I can get NO info on "how" to
cool the tube. I have been looking into stainless steel heat exchangers,
fish tank" water pumps,water chillers,etc. I would like to hear from anyone
who has ever built a cooling system,ran one,etc. From Eimac I was told the
tube needs 7.7gpm to run at the rated dissapation (will never run even close
to that). Most water chillers I see (small ones) only flow about 2-4gpm. And
they are EXPENSIVE. So.....can anyone help out??
Thanks for your time,Stan
