 The last set I had to deal with that had a Magic Eye was a Canadian RCA-Victor A-23, it had two other issues in addition to the burned out 1 meg resistor. The first issue was that the eye tube was seized right in place, the second was that the wires in the cable were baked to death and the insulation falling apart. Unfortunately this used one of those infamous Eby sockets with the Bakelite back on it, the tube contacts are seated in these holes molded in the Bakelite back, and held in by a phenolic wafer, I suppose I could have tried to salvage it but since I had an Amphenol socket with the metal cap I used one of those instead. One thing that I have though of doing was to take the back from one or more of those Eby sockets and hog it out to fit over the back of either a six pin or an octal socket. In another set that had one of those Eby  sockets, a CGE JK76, I connected an octal socket in place with no cap but it looks kind of crude, and is somewhat dangerous.
