Subject: 3D World MF Mounting Jig: Power SourceDate: 2019-02-27 02:12:42From: flash3b 
I bought a used 3D World med. format mounting jig on eBay.  It has a  panel of LED's inside for illumination, although it seems that it was  designed originally for a different light source.  But I bought it with  no power adapter, and it does not say what voltage  power supply it needs. I tried 5 volts  with no success, then 6.  But I'm afraid to go any higher &  possibly damage the board.
 
 Does anyone have an instruction sheet for this device?  Or have one of them with its power adapter, so they could tell me the voltage?
