What do you call a non-Schottky diode?

[Gyro]

X-ray tube, CRT.

The CRT is at least a triode (pentode or more depending on whether you count the focus electrodes etc.)

That would be a project. To get a CRT to function as an amplifier.

You'd have to de-focus the beam a lot to get any significant anode dissipation, otherwise you'd generate an internal cloud of Aluminium and phosphor vapor! There are Beam Triodes though, which have a basic electron gun assembly, firing into a cup shaped anode. They were used as high voltage shunt regulators for things like regulating the EHT supply to CRTs in high end monitors to prevent image blooming.

Beam deflection tubes could be used as amplifiers.

I'll wear that one. Bit of a stretch.

On the subject of "diodes that have far too many electrodes", there's this thing...
