The following is really aimed at Dave WM because he's the guru of cataract removal and because I wanted to include some pictures I think you all might find interesting.
I've pulled the CRT out of the chassis assembly in preparation for removing the cataract, but I wanted to send you some photos to confirm the type of resin used. I suspect that this was a "Zenith" type of construction. The first shot is the only label on the tube. Nothing says RCA. The second shot is the join of the safety glass, resin and faceplate. It was a very easy matter to run a short blade around the circumference of the tube, in the resin. The third shot is a piece of the stuff showing its crumbly texture. The fourth shot shows a screwdriver inserted next to the faceplate and pulling some of the resin away; no serious resistance! What do you think? I suspect that this is a candidate for the "guitar string" method.
