I have a set of flawless 9" tubes from an old NEC GP-5000. Are they compatible for anybody's use? The red tube is an NEC #C9M202P22R.

It is a very early generation 9" LC, ES projector from NEC. It had limited bandwidth and was ES focused.

you sure they are ES focused? The GP3000 was EM focus.

No, not sure, but just assumed because of the age.

Gp-5000 had color filtered (including RED) C-elements and HD-10 lenses, LC housings would be more desirable, than bare tubes

BE careful, NEC siliconed in their C elements, and removing them can be a bitch.
