color crt test jig

[snelson903]

for a long time iv been wanting to build a test jig for mainly color sets ,i have big enough benchs where i could set the chassie on and crt [ in a mounted encloser ] and do most of the work before i put everything back in the cabinet. what im looking for is there a rectangler crt [ tube # ] that i can use a adapters and yoke that is compatiple with the 21fjp22 type crt. or even a crt chart with adapter # and setups , iv seen these test jigs in old test equitment books if anyone has any paper work that might have been supplied with one of these jig set ups . i have 3 vary good rect. crt from 1970 and late 60s i would like to use one of these crt for most type of chassie im working on ,if anyone has any info i would apprciate it. thanks
