A slice of pi (winding).

As some of you may know, the flyback transformer has been found to be bad on the 19CT1 Motorola set. Since it seems pigs will fly before I find an NOS replacement, I tried investigating a few places that advertise rewinding and custom fabricating transformers. One thing that seems to be a common issue is the problem that the old flyback utilizes a pi winding, which it seems nobody has the right equipment to duplicate.

I'm curious to know (I've been learning about the details as I go along), what is significant about pi-winding a flyback transformer, and why a replacement has to be pi-wound? Would there be any way to adapt a flyback from a different set to get the Motorola working again? Are there any options anyone can suggest at this point, or am I pretty much dead in the water?



Thanks,
Joe
