I'm finally getting my PH controller set up after a couple of years delay. I've got a new probe and everything ready to calibrate but apparently I didn't get a power supply with it. It's not easy finding the correct specs for replacement. Some of the ones on Amazon that say they are replacements turn the plug so you can't see the specs in the picture or they blur the pic. The one pic that shows has it as a positive sleeve and negative tip. Everything I have that's 12v is the opposite. Can someone check theirs for polarity? Mine is an older unit but it appears that Milwaukee uses the same power supply across their whole line of equipment. Thanks!

Nobody has a Milwaukee PH controller?
