[NJARC] isolation transformer

[antqradio at sbcglobal.net]

How much power (VA) will the transformer have to isolate?

You can always make your own isolation transformer by connecting two similar transformers which have the same secondary voltage and current rating and a VA (volt-ampere) rating higher then whatever load you intend to isolate.  Just connect the two secondaries winding together and connect the load to the second transformer primary.  To prevent flux linkage between the two transformers, mount the transformers 90 degrees with respect to each other.

The bonus for doing this is that the second transformer primary will be a few volts below the first transformer primary voltage due to m=normal losses.  To put this another way, 126 volts in, perhaps 117 volts or a little more out.

I am looking for a recommendation for an isolation transformer...maybe something with a voltage meter...??? Any suggestions
