Zenith Power Transformer Connections

[EdKozk2]

I have an old Zenith Power transformer I pulled from a set long ago.
I tested all the windings and there fine. I'm not sure which pair of wires
are the 120VAC primary windings. The transformer has 14 wires coming out.
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,
Ed
