Wanted to buy (or barter for something you may need):
Isolating transformer 230-230V - must be more than 1KW, 2KW is even better. Toroidal or square - does not matter. Will pay cash in Auckland.
Will come to pick up.
I will be amending the secondary winding (reducing it) for my lab experiments - so the core should allow that.
Seen on Trademe cheap $15 in CHCH - but that is outside of Auckland unfortunately.
