How about using a modern semiconductor IC hidden inside the box and just
having a couple of ornamental toobs stuck out the top and glowing. A USB
port should just about power two filaments.

Heresy!!

....On a related note, large crates of 6AL5s have been known to turn up on
eBay, advertised for Xmas lights and other assorted uses.

BTW is "boat anchor" the US term for tube based or old dead kit?

Big heavy kit anyway. It's not really dead if it still works..?

Toob stuff is generally iron-rich, so it fits well, although some early
solid state Tek/HP/radio equipment also fits the bill nicely.
