Hi Gents,
I just bought a MAM vocoder from the US with a external wall wart - AC 12 volt 500ma 110 volt power supply.
I want to purchase a 240 volt power supply to avoid using a step down transformer.
The question I have is - do all power supply's have the positive on the center pin of the plug that goes into the unit?
I dont want to cook this box by having the positive and negative reversed
any help would be much appreciated

You stated that it was 12V AC, alternating current (sine wave), so there is no positive and negative. So when you get the 12 V australian one, make sure it is AC and not DC - some wall wart units that are DC have positive in the centre and some have negative. But yours (from what you stated) is AC. Hope that helps.

Just to be 100% sure of what I am asking - the existing wall wart says:
Input 120v AC 60hz 16.5W
Output 12VAC 1000ma

So any 12 volt AC power supply in AU will work?
Thanks Gian

As you can tell I have zero experience with electronics - only using/abusing it to make music

If your looking for one Chris. This might be useful.
All the best

That seems correct Chris but if you are unsure then take the wall wart to jaycar and say I want something to replace this and they should sort you out.

that altronics one is correct. No polarity issues for AC secondary plug packs.

Thanks
You guys are Gentlemen!

Hey Chris.

Let me know when you fire it up... I'm interested in what you think of it.

Personally, I love it.. it can tear your speakers apart.. or can be nice and tame / ELO / Air.

And the white noise unvoiced bit is nasty.

Regards
Mike

Thanks for the speaker tip Mike - so glad i modded all my monitors to have fuses.
After cooking so many tweeters with my Neve Teledistorts I got wise.
Really looking forward to this box for some creative manipulation and abuse - and running it through the teledistorts!
