You have no idea how many microwave transformers have aluminum windings! In my experience, its like 10%!
Ah. I see. I just assumed these were copper windings, because they're copper colored. I've not tried tearing any apart, and wasn't planning to either. Just piling up motors till I have a good haul.

That's what I love about this forum...always learning.
