trashed flat chassis

[sampson159]

picked up a flat chassis zenith yesterday.maybe i should say a trashed flat chassis zenith.no back.yoke.tripler,focus block,transisters etc.basically a cabinet and a crt.looks like it was used for parts?crt tested very weak.never saw a zenith crt test that bad before,so i was skeptical.i warmed it up but still tested weak.the only left to do was to jig it up in a set to take a look.it went in a sylvania gt matic because of the ease to change out.we did a million of these swaps in the shop.when i powered it up,i was delighted to find a very bright,sharp,beautiful picture!tested my nib rca crt and it tested excellent.retested the zenith and it again showed it was bad.i am watching it and the picture is fantastic!yet is tests bad.this crt is like new.green label zenith crt 25vdmp22.the gt matic is looking great with this throwaway crt.retested after two hours of watching time and it came up but still tests weak.
will post pictures later
