The components are glued to the tube and wired with conductive paint? To us in the 21st century, that still seems cool. Early surface mount technology! The resistors are paint! Today... the paths are printed with laserprinters and the toner transferred to the copper side of blank printed circuit boards before etching. Has anyone investigated CNC milling of circuit boards? No etchant would be required! (Not sure how a tool could be fine enough and strong enough. Laser? Plasma? Really tiny steel bit and lots of time?) Photo D looks like a retro integrated circuit!
