I took the transformer apart and the coil former was in bits. So my call out Videokarmaland is do any of you have a spare injection coil/transformer? (It is Zenith part S-66788 and it looks like it was used in most if not all early Zenith color sets from 1962 to 1967. Note it is mounted in a standard aluminum can and has 8 terminals).

Failing finding a transformer, a two inch length of coil former which takes threaded ferrite slugs would do. I am prepared to rewind the transformer but even the formers are hard to find these days.

Any help would be sincerely appreciated.

Recheck your part number - I have a NOS S-66788 (Zenith 20S-66788, helps to know the prefixes for Zenith lettered parts!) My S-66788 is a sound quad coil, and looks nothing like yours pictured.

Your transformer may be an S- numbered transformer, or a 95-XXXX number.
