[GreenKeys] Nicks tube thing.

[steve bennett]

 Nick,
  I love your creation. Thanks for the detailed explanation.I have a few magic eye tubes I bought to play wiith.I also bought a kit to power them.I never got around to building the power supply kit but I am able to light them upwith a tube tester except for the Russian tube.I was never able to light the Russian magic eye on the tube tester.Maybe it is bad.

 Steve,
All tubes are functional but there is no purpose behind the entire thing except a conversational display.
I met a nice guy online form the Ukraine - he provided most of the tubes. He is an electronic engineer and he helped me to bring most of the tubes back to life. Unfortunately I lost contact to him - hope he is not a victim of Covid. 
The tubes all need different voltages - some of them just 12V which was easy to accomplish. The magic eye needs around 155V-175V, the spinning Decatron around 250V if I remember right, the two vertical dot matrix tubes only 2.5V and the big spark generating tub a whopping 8000V at a super low amperage. There is a blue temporary switch for that particular tube on the lower front right of the case. And there is a 120VAC indicating neon bulb inside of what you refer as 'Edison socket'. The second one from the left in the back row is a microwave bulb and not hocked up to anything - I have no knowledge to test this particular puppy.The three indicator bulbs (8,  K,  and ohm symbol) on the front panel also run on 155VDC.The very tall, skinny one on the far right between the two dot matrix bulbs indicates a beautiful orange light going up and down by a motorized potentiometer. Don't ask me how I accomplished that - it's a real redneck solution, but it works :-)

Ralph,
I created this tube display a couple of years ago - just for fun and entertainment. You are right about the tube prices. I could've bought an exotic car for that :-)..... don't tell my first lady that  :-)  :-)  :-)
2 pics attached - enjoy !
