Weird Raytheon Tube

[@TechneMoira]

It looks like a high voltage high frequency triode tube to me. The fact at least two element connections are connected to two separate caps on the glass envelope suggests high voltrage for sure. The exact type is unknown to me. My best guess is therefore a type of triode

Maybe it is a bulb meant for high altitudes, maybe even on the outside of a plane.

Three wires in the stem. Center-tapped filament, or separate cathode? The plate support does make it look like a prototype.

precision percussive maintenance is sometimes the only way to fix a tube, have had to do it before on high voltage beam tubes and some transmitting tubes, mostly tesla. As for the Raytheon tube, i suspect it a prototype made for marketing purposes.

Should not be that tough, there are old tube data online. It is likely either a transmitting triode of around 50-150w plate dissa pation or thyratron, Something like Eimac would be a 75 or 150T

[@Shadowfoxxy30]

it's a transmitter tube
