Thanks Bob for that interesting piece of info, I didn't know that they could operate with B+ that low and still produce full raster. BTW your Philco radio videos are very interesting.

As to the flyback, I think it's original. There's a story with it though. When flaking all the tar off to recoat it, I discovered a hair thin wire sticking out of the side of the over wind. It was near the inner core of the wind, next to where the wire from terminal D (HOT plate) comes in. I'm assuming I broke something when I removed the tar, and the logical place for this strand of wire to go was to the wire that comes in from D. So I connected it there, but who knows, I may have it wrong and be causing my own problems. I'll look at subbing a yoke this weekend, but I'm suspicious of the flyback.

UPdate: I carefully cleaned the side of the over wind with alcohol, looking for a potential other end of that loose strand. I couldn't see one, so I severed the connection I had made and tested. The 360 ohm reading between D and the rectifier cap is now infinity, and when powering up, B+ still drops to 230V. I'll redo my repair to the fly and sub in another yoke. I'm less suspicious of the flyback, but it still may be a problem, just not where I thought. Glad I haven't coated it yet!



Apart from this major issue, I think I have the rest of the set working, as near as I can tell.

Cheers,

Adam
