Re: NST Depotting Experience +

Most that i've come across with gfi are potted in epoxy, and the chemicals that are able to remove that are near $100 a gallon (which would probably remove the enamel off the magnet wire too). If you can remove that without destroying the transformer, let us know the secret, I've pretty much given up on that idea.

I have access to a large pile of relatively new defective FranceFormers that
have the ground fault circuitry.  Sounds like I should be able to remove the
ground fault junk and the transformers would probably work fine again.  Am I
thinking correctly?
