Flyback for Admiral 20A7

[Alex KL-1]

Hello folks of Videokarma,
In my small TV collection, I have 2 tube TV's but none are working anymore.
The dreaded flyback issue...
I want at least one tube TV working in my collection!

These times, is becoming extremely expensive to acquire a tube TV, since most people loves old furniture, and old TV's in general have beautiful cabinets (I assume that people discard the ugly ones and prices are on the stratosphere (or shipping, due to weight, or both). Or, if is cheap, have missing parts, or with some vital part damaged (tube, flyback...)

I'm trying to find a compatible part, but without success.
For the Admiral TV, model 20A7, I don't have the part list of this model. The actual flyback has a code on it: 15A1248-2, but I suspect that is one replacement part and not the original one.

I'm motivated to even change the H circuits on this TV (or the Telefunken) if I find one flyback compatible with it's yoke (20mH total inductance for H part), or if I find a flyback + yoke compatible with 23" 110° CRT. No need to match the V part; I can adapt the circuit if I need. If differences on auxiliary circuit exists, is only a matter to wind some wires externally.

I see a lot of flyback and yoke models on the Early Television Foundation, but I don't know a guide for matching flyback, yoke and CRT.

Any advice about compatible flyback for these conditions (original, compatible or for changing circuits) will be greatly appreciated!
