Wanted to buy autotransformer also known as variac. In Auckland
The bigger the better. I've seen 500W - hugely overpriced in Surplustronic and same on Trademe. Have not seen 1-1.5KW

Also wanted isolating transformer 230-230 1.5KW or more, if it can be dismantled - better.
Also wanted 1.5KW or more autotransformer (sometimes they are referred to by uneducated sellers as step down transformers) which I can dismantle to rewind it. Isolating transformers are normally filled in with compaund and it is hard to modify them.

Hey, have you listed a price, location and how much shipping would be to other parts of New Zealand? Also if you are asking for a PM make sure your Privacy settings allow your account to receive PM otherwise people can't contact you. Also note if you are selling something we ask you to offer to other members first. Links to private sales (including Trade Me posts) aren't accepted anymore and will be removed.

I've got a 2000w step down transformer. Output is 220v-240v >110-120v like one of these: http://www.trademe.co.nz/building-renovation/electrical-lighting/other/auction-799424779.htm

I had to replace it as it would no longer grip the pins of my appliances. I took it apart and tried to readjust the contact plates by bending them.

This worked for a couple weeks but now appliances will not make contact unless you twist the plug to a weird angle.

Ended up just buying a new one. Was going to keep it in the garage to tinker around with. Pm me if this fits the bill.

Ouch that is really expensive off trademe for one of those.

OP, have a look on aliexpress. A friend got a whole heap of stepdowns from a seller on there for a great price, sent by DHL for under half what they would have cost locally. Once you hit 20kg then it becomes freight rate which is considerably cheaper. Suppliers even managed to put a legit aussie plug on them with a legit looking cable. We werent going to cut one open to see if it really was 0.75mm area, but they seemed alright and the load was small so imatterial really.
