There are almost infinite permutations of core material, shape, size
and winding counts and wire gauges. The chances of finding this
custom design are very slim. This one should not be very hard to wind
if you can find the core. There is also something very satisfying
about making a transformer with your own hands that works just as well
as anything you can purchase.
The 2 turn winding could be wound with the same sized wire as the 142v
turn coil, and the two 7 turn windings should be wound with a pair of
parallel or twisted wires rather than two separate 7 turn coils for
Have you searched, yet, for a source of the core?
By the way, this post would have been better posted on the
sci.electronics.basics newsgroup. There is more help for beginners,
This one is intended for discussions between circuit designers.
