Buy a 3KVA transformer from Heybour for $500.00 and be done with it. Small, compact, and it will work better.

Yes.

Or buy the materials and wind it yourself. It will be some work, but the cost will be at most half that much, and you will learn something, and get the satisfaction of having done it yourself.

Or make a switching power supply. It will be far more complex, you will have to learn a lot of things, but the end result will be small, lightweight, and the output will be precisely regulated, hum-free and short-circuit-proof.
