[Amps] Roll your own transformers

[coffey]

Plate transformers: After using a "pole pig" for 30 years, 2600 volts in a voltage doubler ckt with variac, it's starting to hum a little.
these days. I am thinking about doing a rewind this winter, building a jig, increasing the size of wire on secondary, and decreasing the size on the primary for more current capacity, new paper etc, and changing to a bridge rectifier ckt. Can someone recommend a book on the principles and the practical approach to this kind of project. Maybe someone has tried this already and either had great success or would never do it again.  thanks, K4AVC
