Well obtaining supplies to wind transformers isn't easy but with persistence is possible. eBay and Amazon have been wonderful sources as well as Temco Industrial. I would like to deal directly with more suppliers, but you get what you can where and when you can.
A couple of questions I wanted to run up the flag pole to see if anyone here knows anything.
1) Anyone know of any disadvantages of using 200C magnet wire compared to 150C? Is its insulation coating thicker?
2) Is the primary reason for tape between windings to reduce arching in a transformer? And subsequently, in lower voltage smaller transformers would this even be necessary, like in low voltage audio applications?
3) When does multiple interleaving start to become counterproductive by introducing other problems or does it? For example, the most basic interleaving is 1/2 primary, the secondary, and the final 1/2 primary. But I prefer 1/4 primary, 1/2 secondary, 1/2 primary, 1/2 secondary, 1/4 primary interleaving. I am wondering what all the advantages and disadvantages are with side-by-side windings. Where you have a bobbin that is split to separate the windings. To me side by side would be less capacitance but more losses.
In some ways, I am finding experience to be the best and only teacher in this game so far. So I try stuff, measure, test, and then try something else. Sure seems to be the slowest most laboriest teacher, but what choice do I have.
