As my good friend John Folsom (aka Mr. Early Color TV) told me when I first got into this hobby......."It's all about the spares" I am sure there are people out there who probably have a good used spare, however the minute you sell your only spare, that is when you will need it to fix one of your sets.

It is a rare part indeed. Attached are photos of my NOS spare, the improved version. (probably worth it's weight in gold)

You are correct, your Seville is a "late production" set. However that does not necessarily mean that the flyback is the new improved version. The original flyback design was very problematic. Many many failures. That prompted RCA to redesign the flyback and the replacement was far more reliable. The original version flyback was stock #100409 and it will have the RCA drawing number 1106237-1 stamped on the frame in black ink letters in the same place you see in the photo.

The improved flyback is stock #101959A and will have the RCA drawing #1106237-2 as shown in the photo of my spare.

I have discovered over the years, that you need to buy backup sets that are in poor condition, so that you will have a source of spare parts for the sets that are worth saving. I do not subscribe to the notion that ALL sets should be saved. If a set is a POS then use it for parts and canabalize it so that a nice quality, or rare set, may live again.

Your Seville is a rather common variety 4. Spend some money and buy a high end 4 (Director model or better) and keep the chassis from the Seville as a parts set. That may be the only way you will find a replacement flyback. You can then keep or sell off various parts from the Seville as you desire.

I just finished restoring a CTC4B chassis that is going into my Cheltenham. The HOT current draw on this properly restored chassis is running a cool 175ma, so this is not an impossible current specification.

I truly feel your pain. It has happened to most of us at one time or another. All is not lost, there is always hope that you may get lucky and find a replacement, however it may take quite some time and more than a little luck. Perseverance is the key. Hang in there and just keep looking. Eventually you may find a parts chassis and if lucky it will have a good flyback. Unfortunately the flyback is the first part to be canabilized. That's why I say you should set your sights on another complete set, preferably a Director or better.
