I didn't think of this because I don't like custom transformers :)

I think in small quantities (currently anticipated are batches of 20) they
are not "friendly" -- but I've never been there, done that.

How do you get/make the transformer for something like this in those
circumstances? (Hand-winding is not an option, I guess :)

Thanks,
