Tube type UXCV11 Cetron???

[Daniel Donnelly]

Sounds like a great tube to allow new hams to actually learn how to
tune a transmitter !
I had a ( I beleave that it was a "Swan" that would blow the final
every time the wind would swing the antenna.

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.
