[rescue] S: IBM 3486 replacement tube

[Patrik Schindler]

Hello,

I'm searching for a electrically defective or a badly shaped 3486 or similar terminal with a similar CRT, preferably in Europe (shipping expenses!).

https://de.m.wikipedia.org/wiki/Datei:IBM_3486_terminal.jpg

I have one looking almost pristine, suffering from a CRT with a broken neck.

Of course I can't find my notes about the precise tube type. Duh! But I remember that Google found absolutely nothing related.

The main problem is the screen curvature which needs to match the front bezel's, while electrical parameters are largely compatible between types. The CRT has a surprisingly flat screen as can be seen on the picture. As such, any other non-IBM terminal might have a matching CRT. I believe the monochrome 3477s have tubes with a thicker neck and different pinout.

Sourcing such a tube would be great. Sourcing an amber one instead of the default green one would be amazing!

Offers welcome!

:wq! PoC
