The Zenith number is 95-3172. From what I could find from a google
search is it was used in a 23GC45 and 25GC45 television. The Sam's folder is
supposed to be 1558-2, a mid seventies set. Of the 14 wires, 4 pairs are isolated. The other 6, are taps of a single winding. One of the pairs have plastic insulation, the other 3 pairs are cloth covered.
Would any happen to know which pair of leads are for the Primary or happen to have a schematic of the power supply ?
Thanks,

Can you take the bells off the ends of the transformer to potentially see where the leads wind up inside? Often you can get a feel for things by how deep in the bobbin they are, if they're insulated particularly heavily, or if you're really lucky you can observe the wire gauge of the actual winding where it connects to the lead wires.
