By "CRT" I really do mean CRT. You are talking about the combination of CRT and yoke. Do not confuse these two; just because the yoke sits on the CRT does not make the collection a CRT. You may wish to update your sticky to make this point explicitly clear.
The CRTs themselves are electrically interchangeable to a 100% degree, as far as I am aware. If you encounter an incompatibility with the yoke connector, simply leave the yoke with the Mac it came from, and you will be safe.
The only CRT-specific quasi-incompatibility that one might encounter has to do with the orientation of the pins on the CRT base. On some versions, the pins are rotated. Rotating the cable to accommodate sometimes takes up what little slack is left, making for a marginal fit. A solution is simply to lengthen the cable.
