Most of the RCA flybacks we changed back in the 60s and 70s were in the summer. We'd get a run on them whenever we had a stretch of hot humid weather. Today, most of us have AC which would mitigate that factor at least. Plus, most of us don't run our vintage TVs 50 hours a week either. Seeing that a good portion of the RCA flybacks that failed did so by burning a trail from the 3A3 cup to the core, I would carefully clean any vintage fly boot with alcohol to remove any remnants of dirt or ciggie smoke left over from the old days that might show the arcing gremlins the way.

This is his video where it happened.
https://www.youtube.com/watch?v=anXLhlAefG0&t=4s I kept saying to myself, “it's gonna burn up, it's gonna burn up!” and sure enough.. as soon as I saw his screen dim, and shrink I knew exactly what was happening, cause it did it in mine.

 That SS stick rectifier he pulled out looks exactly like the EDIs I used to use. I was skipping along the video so I didn't hear if he said what kind of rectifier it was. I don't think this would be an issue with using stick rectifiers with the 16 necessarily, but just a substandard device that would fail in any color TV. That rect will probably still be able to replace a 1X3 series since the B&W requires less HV and current than the 21" color tube. During the Christmas break, I'm going to see if I can find an EDI 3A3. If I can find it, I'll send it to you for experimentation if you want to screw with it. John
