Are you shure the adapter in the picture came with the plugiator? Because its labeled 12 volt.

On these kind of adapters center pin is always plus as i have seen through the years. So just look at the specs for an appropiate adapter. I think a standard boss or chinese adapter will do. Nowadays we have a lot of adapters laying around....maybe check on your attic This should be a standard part in any electronics shop. Just make sure you check the specs. Just make sure i can deliver 500mA...more is not a problem..less could be...

thank you Ray and al-bot, I found an adapter and I powered it up, all seems to work normal, but at a time the unit shut itself down and restartet immediately. I measured the power...it was 7,4 volt althaugh it was declared 9 volt...I will try annother one...but I must say the crakles when I switch the instruments or the programms on the plugiator isn't nice..
