The museum also has some tater video from RACS in France, shot before they closed.

The guy who shot this video was mainly taking a 21AXP22 picture tube down there to try and get rebuilt. It was from a rare (Dec 1954) RCA 21CT55 TV I sold him. The 21AXP22 (the earlier version of the 21AXP22a) had the wide spectrum phosphors complying closer to NTSC spec. He explained to me you could tell as (with tube not running) they have a dull green look.

These tubes had a metal bell (at 21kv when set running!)(thus they are enclosed in a white nylon-like plastic in TV.) The rebuild was not a success, it cracked. Scotty had the idea to wrap it in Alfoil for the vacuum oven phase - an idea the owner disagreed with in retrospect.
