Forgot to mention: original owner who restored was a pro who supplied the Smithsonian Institution with their CT-100. He told me that long ago (way before I bought) he treated the picture tube with something called vacu-seal which I believe prevents corrosion which could lead to loss of vacuum seal, so the 15GP22 has been well protected. Also, I turned the set on yesterday (6-13-05) and both picture and sound work. I took four screen shots and will email them to anyone who wants to see (click the ask seller a question link to email me).
