[GreenKeys] Vacuum tubes in TTY power supply

[Nick]

Thanks to all of you guys for the helpful inputs on this topic. I am trying to put a working  vacuum tube display together. Wow, much more complicated than I realized - but I learned a lot lately and thing are slowly coming together.

Thanks again,

I have seen a picture about a year ago (or was it a YouTube video, can't remember) of several blue illuminated vacuum tubes inside of a teletype power supply / rectifier.
Does anybody knows the name/number/model of these tubes ?
