Generally the design of the lopty's overall inductance, turn's ratio, winding taps, winding DC resistance, coil mutual inductances, operating voltage and design of deflection yoke it operates with, is pretty specific to the particular manufacturer & set model or close model to it. Unlikely you'd get a drop in replacement for one from another manufacturer's set, unless it was just the same set re-badged.

Do you have a list of makes/models that used an identical transformer ?
I believe Fernseh converted a TV22 to use a Ferguson Potted Line transformer quite a long time ago and also my friend Trevor has done this as well.
He recently has been expeimenting with other television line standards on a TV22.
