I run Win10. The software does not work for me.
But,-there is something else that works:

Very cheap "software" for calculating output transformers plus all the hardware you need.

If we keep doing what we are doing, then in the future, if there still are tube amplifiers, the design will be done by AI.
So many experienced old people are going away, and so few young people are learning by doing all of it themselves.

There are a few people here that seems to know more about winding transformers than most.
Wouldn't it be nice if that knowledge was gathered and organized into a more or less large downloadable document?
As it is now a lot of info can surely be found, but it is presented in small and incoherent pieces here and there in a zillion threads.

On (the archive of) Patrick Turner's website you'll find a complete write-up.

Unfortunately, information on making audio transformers is not easy to pack into a book, as every type of transformer requires unique approaches and studies.
I find that the most pragmatic way towards transformer knowledge is to illustrate already built and studied examples of transformer geometries. Transformer knowledge is very much made by a lot of trial and error, then studying the work with reverse engineering and then looking for theoretical explanations.
It is easy to get confused and to follow a wrong lead, because with transformers, too many parameters affect each other, like a mathematical equation with tens of unknowns. The more you build, experiment, measure and study, the more variables you get to isolate.
I believe each type of audio transformer: OPT, step up, step down, 1:1, input, line-out, SE, PP, phase splitter, etc, etc, require their own unique book/manual.
If I were to give the best simplest advice to anyone that I did violate and now regret - please don't throw away your "failures". Keep them in stock for further studies.
Most textbooks concentrate on leakage inductance and capacitance, but do not mention other crucial factors, such as resonance formation, capacitance distribution, the importance of secondary layers connections, etc, etc. And there is seldom an universal approach. For example, one type of transformers can be more tolerant to one solution than another type.
