What is being discussed here is a 'test CRT', that is a CRT a technician
would keep on his test bench to verify the operation of a TV chassis
that is separated from its own picture tube. 8-inch monochrome test
CRTs are quite common.

CRT = cathode ray tube = 'tube cathodique' in French

Sorry I don't know the usual Italian word, maybe you can tell me...

Test catodico valvola

Here's a thread with more information
 

I give up. :sigh:

Who thinks that tube was worth $202.50? :thumbsdn:

The winner I guess.:dunno: I've certainly spent more on rebuilding B/W crts.

Hopefully if it was someone here they'll be kind enough to report on how it performs.
