Hey all, I bought my UA-5 about a year ago and it came with a nice black 12 volt batter, like a walmart lappy battery kind of. Anyone I lost the charger for it and called Oade and got the specs for buying a new charger from Ratshack. The only thing I forgot to ask is if the charger is tip positive or tip negitive. Could someone that has the charger look for me? Id be VERY grateful as I have a Phil show to tape tomorrow! THANKS!
