Looking for CTC-9 flyback

[columbia]

Hey gents. Well, I'm in a bind. I'm looking for a CTC-9 flyback for my 5th anniversary Boswell. I had a burn- through of one of the primary windings and she died. I've searched for weeks with no luck. Even Moyers seems to be out of anything for a 9. So I'm hoping there's a lonely extra one sitting out there somewhere on an old unused chassis or sitting on a back shelf somewhere collecting dust over the years. Just name your price and I'll do my best. I just feel that it's important to keep these old girls running. So, much thanks to all and keep 'em running.

there is a good video on re waxing flybacks, can't recall where its posted but a search should show it up. A bad fly was brought back to life.

Wax has nothing to do with the primary winding.

thanks for the info on the rewaxing of flyback transformers. It was pretty interesting. But, yes, unfortunately that won't help with the open in the primary. But thanks anyway.

Hi, just thinking loud, but is the open winding layer wound or wave wound?

If it's layer wound, what about careful stripping of the bad winding, counting turns between taps and marking their location, then a good rewind with new magnet wire of the correct gauge #? It is not simple, but not impossible either, it just takes lots of time and patience, and if a replacement is unavailable, this may be the only solution. If you follow this route, don't forget to impregnate the winding with abundant anticorona lacquer, as the interlayer paper alone is not enough insulation.

what is your part number. and cross refrence number. i have a lot of flybacks. steve

Wow, thanks for the great ideas and info. Hey RCAman, the RCA p/n for that flyback is 106359. The Thordarson p/n is FLY284. The Merit p/n is HVO231C. The Triad p/n is D301F. I don't know the Halldorson cross number or if there even is one. If you have one, I'd be grateful. It's like waiting for a liver transplant doner or something. Otherwise, I will have to look at a rewind attempt. Can't give up on these beauties.

Easy to adapt another rca flyback in there. Rewinding is sure death. I tried that once and almost killed myself. There are hundreds of feet of wire in there.

How does rewinding kill a person?

I had several of those early roundies, but I sold them, for lack of interest at the time. I sold them dirt cheap. Forty years later I regret it. The same problem as the rest of the collectors. Lack of storage space. I probably had three of those chassis with good flybacks.
