Hi Paul.
It's very much doubtful that a 23 inch CRT would fit in a domestic oven.
Certainly it's not a job for anyone that has any doubts with the safety aspect. I'll not be doing it nor would I attempt it. The fact this one is cracked it could suggest it may be easier to remove.
The CRT that is low can of course be made safe by releasing the vacuum and the faceplate then removed in relative safety.
I'll leave it up to Fernseh and what he wants to do. Of course the CRT needs to be tested in the first instance.
I wonder if the likes of Autoglass could do an invisible repair?
