Hello Steve,
That sounds interesting! Would you like to share your knowledge on how to
build your own transformer, I have been looking on google but, not much
information in the first 100 results :)
I already wanted to experiment with trying to rewind the secondary of a
MOT, but if you had success building your own in a different way, I rather
try that approach.
Best regards,
Sebastiaan Draaisma
