I have an HPA-1 and was wondering if there is a way to get the original wall adaptor for it, or at least get some sort of replacement equipment that can supply power to the HPA-1.

maybe I can make my own? all I know is there are three pins on the DC 12V input plug; most likely a ground, positive, and negative pins.

thanks a lot.

alright, I was going to contact them... but was wondering if there were cheaper solutions that I could possibly make myself.
