Here’s a simple easy to build Isolation Transformer that you can buy from All Electronics.

Here’s what you need:

1x 120VAC Output transformer

1x outlet connector

  1. for 110v use do you just apply voltage to f1 and s1 or should you parallel the primary windings ie: connect s1 and s2 together and f1 and f2 together?
