If my memory serves me correctly the Stanley Steamer was actually a vapour
phase tube (a 3CV*** or 4CV*** as opposed to a 3CW*** etc) in a boiler rather
than a water cooled tube.
Eimac published this as an amateur service newsletter or similar. I do have a
copy somewhere if you'd like me to copy it. Actually I have all the Eimac
bulletins and keep meaning to scan them when I get some of that rare resource
called 'time'

There was an article in QST many years ago called "The Stanley Steamer"
which described water cooled tubes. I believe ETO built an amp based on a
water cooled tube that Eimac made that had 1500 watts plate dissipation. The
principle being it takes 539 calories of heat to convert 1 gram of water at
100 deg C to vapor if I remember my thermodynamics correctly.
