I have several 12 volt wall warts and a mini inverter/power supply with various plugs and which can be set to 12 volts. Problem is that the 12 volt barrel socket on the PC55 is a different size to the plugs on all the wall warts. Also the power supply just doesn't seem to want to power either of the PC55 decks I have. Don't know if there is a polarity issue as well as an odd sized plug, anyone out there have the answer or a psu I could buy?
