Another odd one, the Charactron, a CRT with a shadowmask that has the alphabet punched into it, with beam steering plates used to select a particular character 'hole' then further plates to steer the beam to the screen. Used to produce microfilm and documents, a version was also used in the US SAGE system to put text annotation on to CRT s creens alongside the usual Radar images.

And Bussmann have fuses branded Fusetron.

Elektron magnsium zirconium alloy castings:

With materals with names as awesome as that you can let Elektron get away with it!

Robotron.
A coin-op arcade video game in the 1980s, in which the playfield resembled a particularly lurid acid trip...

G6Tanuki · 18th Aug 2023, 7:50 pm

Robotron was also the 'brand' for East German computer gear in the 70s and 80s. Generally using clones of Western designs like the DEC VAX, acquired via a range of often questionable routes.

You didn't even need to do that. I bought one NOS from a watchmaker who was closing down. Got home, sat reading, and I wondered where this hum was coming from?

When I found out, I took the watch back and swapped it for a quartz one. I wish I hadn't.

No-one seems to have mentioned 'Klystron' yet! They have now.

Reminds me of an Elektron Ladder that I used to hang about on.

Missed that: must've had 'tron fatigue'. I did look. There's certainly a lot of mileage in it! 'Oh, we'll call it a thing-tron or whatever...'

Have we had Selectron yet? ( brand of valves )

Phantastron oscillator circuit.

Mmm. Is that not Semikron (or maybe Semicron)? Semitron does seem to be a manufacturer of the plastic that semiconductors are packaged in, though.

Some more Tron memories,

Haltron. They were one of the big valve rebranders in the 50s and 60s, often advertised as 'for export only'.

There was also a US?? Valve brand called Reliatron. And when I was working in the US back in the early 80s there were a bunch of UHF valves used in Military and aerospace applications that were entirely metal ceramic construction, designed to handle crazy G values and vibration , though I don't think it was an official designation these were known as Huskytrons.

A number of these Huskytrons found their way into amateur 23cm TV transmitter receivers in the Dallas Fort Worth area...

Malcolm G6ANZ · 4th Sep 2023, 3:17 pm

There was a treatment machine using cobalt 60 source called the Mobaltron. And another source machine called the Selectron.

russell_w_b · 22nd Sep 2023, 9:19 am

Just thought on there…. Our HF transmitters used valves that were hypervapotron cooled.

The General · 22nd Sep 2023, 12:22 pm

There's the Circlotron, a valve audio amp designed in the mid 50s which had the output valve pair in a bridge configuration. It promised low distortion but needs three power supplies so didn't catch on. The Philips AG9006 is an example.
Mark.

Ultron, a valve brand from Belgium.

Phasitron, a valve type for FM modulation.
