I don't know if magic eye tubes are still made new, but you can usually
find them at ham radio flea markets.  These are a good source for anything
exotic or old.  Since you're in Framingham, I recommend the Heavy Hitter's
Hamfest at the Topsfield fair grounds July 24-26.

You'll need the usual tube voltages.  As I recall, they are triodes, with
the plate current (controlled by the grid voltage) controlling the amount
of "wink" (or whatever you call it).  I've got some schematics at home
and can probably get pin-outs and voltages if you can't figure it out.
