Look like LEDs inside.
i thought that those were actual vacuum tubes
They look like real tubes, which are mirrored inside (to retain heat I guess). But look more closely and it would appear that a circle has been cut out the top and LED devices put inside to create the images?
(Useless) tube triva: the silver coating in valves is generally the getter coating on the inside of the glass tube.It's a reactive compound that absorbs any remaining gases the vacuum pumping process missed.
And knowing is half the battle...
Thankyou, now we know!
I like tubes, and I like chess! Double yey!
