Hello all, About 10 years ago, I built two 'boilers' for GS-35b tubes, totally for the heck of it.  To date, I have not actually used either one, as building a new amp was not high on my list of thin

I seem to recall the Eimac handbook "Care and feeding of power grid tubes"  having a section on water cooling.  The only thing I recall being water cooled were the 100 Kw plus SW transmitters made by

Having spent many years of my life (in another life. I left there in 87 and went to college) working with induction heating from KHz to MHz and air cooled 2 KW to 6KW water cooled into the hundreds o

Not necessarily against it, but because of the viscosity, I'm reasonably sure an aquarium pump would not work.  There's a wide selection of aquarium pumps out there to choose from.  Keep in mind, tha

While it was a very long time ago, I recall as a kid I got to go on a tour of the old KVOO AM broadcast station in Tulsa. Their tubes were water cooled and I recall the engineer showing us their dist

I concur with Roger, and have always been taught to avoid using Brass fittings in a high resistivity pure water system for amplifiers. Zinc leaches out, but then again, I don't have systems with rout

The system I worked on was installed around 1960 and AFAIK it came out of service around 2000 - 2010. As for the copper oxide, the  foot and a half to two foot long anodes of the tubes  in the 200+ K
