Default Re: ILP transformers

110v primary means the only market for such a tfmr is the States I guess, which means having to post it which is uneconomical. I've removed the potted core out of several toroids by drilling small holes and then chipping it out with an old screwdriver or chisel. If you carefull it can be done with damaging any windings.

The problem you might come up against is if the primary has been wound for 60hz, better to pull off all the old windings and start fresh maybe or maybe not as the windings will be connected in series. As the core is 500VA that means there's fewer windings to pull off/wind back on.

Curiosity hasn't killed this far.
