from the antiqueradios.com forum:
"The UX-CV-11 is a low mu triode with about sixty watts of plate
dissapation. It has a metal UX style base which will fit either the standard
four pin tube socket or a baynet type socket. It has a graphite plate
stucture and a grid made of heavier wire than its counterparts. I believe
the filament is rated at 7.5 volts. It was a tube created by United
Electronics for diathermy use and that is the only place I have seen them.
Regular contemporary tubes would not hold up in diathermy service, since the
tubes were used as self excited oscillators and the grid current could run
to high amounts when the pads were not loaded properly, or the patient would
shift their position on the pads. This large grid current would shorten the
life of most tubes, so a special line of diathermy tubes was created with
massive grid structures to allow for this type of operation."
Hope that helps a little, 73, Brian KA9EGW
