12" Sony CRT on eBay

[andy]

I think just about any 27" CRT will work in that except for the fake trinitrons of the mid 90's. Sony made a bunch of CRTs that used a regular in-line gun instead of the single lens trinitron gun. Obviously, the yoke and pinout would be completely different on those. You will probably have to set the H Stat control all the way to one extreme to get a recent CRT to converge because their newer CRTs are designed to have that pin grounded instead of adjustable.
