    Hello,

    I recently got 6 GAM TwinSpin Gobo Rotators from a lighting rental company for a great price. Only problem when I got the units, I found 4 were missing the power adapters and the two that had adapters, I can't make out the label to see what the specs are so I can purchase substitute adapters. Can anyone tell me what the specs are suppose to be?

    I've written GAM/Rosco three times about this and no one has replied back to me.

    From the two spec sheets below, it looks like the motor requires 12vdc at 300 milliamps. I'm not sure if it requires any kind of special wall wart to allow being plugged into a dimmer if you want a console to control it. To just run it at full speed, any 12vdc 300ma power supply should work. The addition of a 100 ohm pot allows variable speed control. I just Googled "GAM Twinspin" by the way.

    Keep in mind that you can use any 12v adapter as long as the current is at least 300mA. Meaning if all you find is 12v 500mA, that will work too.

    Pay attention to how the center pin is supposed to wire in - whether it's positive or negative. Having them swapped stands a good chance of damaging the equipment.

    Will probably just make the motor run the other way!

    Haha, true. I know my Smart Move's have some circuitry in them that could be messed up but I'm not sure about the Twinspin. Capacitors in particular are not very good with changes in polarity.

    Edit: Just looked at the Twinspin - wow, that thing's just a motor on a plate. I was assuming it was more like a Smartmove with sensors, built-in modes, etc.
