Just bought two of the Non-Legacy Powermasters. Like new. I hooked them both up to test, just to be sure they work well - they do!
But, the Cab-1 "turn of the knob to voltage increase ratio" is different on the two units. On one, a 360 degree rotation seems to go from 0 to 18 volts. On the other, it takes about 5 complete rotations of the big red knob to get from 0 to 18 volts.
Seems like the step rate is different, but the documentation doesn't say you can change the step rate.
Any thoughts or ideas?
Interesting side note...on one end flap of the box, the part number is 6-12867, on the other end, it's 6-12687!
