My Powerbox Advance is brilliant but I'm struggling to find a 12V supply plug that stays connected. I've tried a couple of different plugs but they all cause constant disconnections. The cause is poor quality. The positive connection is just the tube within the plug and there is no means of ensuring a good connection to the positive pin in the socket of the PPB.
So I wondered what plug other people use for the 12V incoming supply? Anyone got a suggestion for a good quality 5.5mm x 2.1mm plug?
Cheers
