Great find! Looks like long-lost child of OG-3 and A-201. Where on the
Earth are you finding all those awesome and unusual tubes?

BTW, we have a proof of the universal quality of the True Technology! If
we stayed with the hot-rod-in-the-vacum light there would be no
flickering. All those fluorescent tubes, cfls, leds... smoke and mirrors
they are. Neons are excused, they are supposed to flicker. ;)
