Hello all,

I'm building a vintage inspired sound system for my workshop and for the amplifier I need a dual 12v power supply, three wires: 12v-0-12v.

I ordered a MM-2018 from Jaycar after seeing it recommended for similar kit amps on Trade Me, but it turned out to be 24v-12v-0 (the product picture on their website is misleading and I was in a hurry, so serves me right I suppose). I can't seem to find what I really need on their website and I couldn't make sense of their reply to my inquiry.

So my question is, am I just misunderstanding the labeling and can I still draw dual 12v from this? I suspect not, so can I alternatively split the 24v to get two 12v? I'm not sure if that would be wired in parallel or series.

Any help would be much appreciated, thanks!

Same thing, yes,

Take the middle one as your 0v and put the other 2 into the bridge rectifier. Someone told me there was a difference based on the orders of the windings or somthing between a 12-0-12 and a 0-12-24 but I cant see any difference on the outputs of the ones I have here.
