WTB: 7" Projection CRTs

I'm looking for a set of 7" projection CRTs for a mid 80's Sears/Sanyo front projection set. The type numbers are 180YB22R, 180YB22B, and 180YB43. From past experience, most common 7" projection CRTs would be electronically compatible.

I used to have a stash of good projection CRTs, but they didn't make the cut when I moved 10 years ago. Hopefully someone who didn't move still has some that they don't know what to do with now that the market for used NTSC projection TVs is nonexistent.

I scrapped a IIRC Mitsubishi projo CRT set a while back and kept the CRTs. Not sure if their good, but I might be able to test them. I'll get you the tube ID numbers this evening.

Thanks, some Mitsubishi projection TVs had magnetic focus which won't work in this set. You can tell because there will be a large focus coil on the neck.

The red one is a Hitachi 120CZB22(R). If you think that will work I can post some pictures, and try to test the trio with the homemade universal adapter on my B&K 466 CRT tester.

There is some raster shaped burn in...

Thanks for checking, but that won't work. The 120 is the diagonal screen size in mm.
