CPC 3010 12 VDC conversion

The original transformer is removed and replaced with a custom built system that accepts 9 - 36 VDC power and gives out +16.4  and -15 VDC. In the modification made earlier the -15 V has been connected to the test point 14 instead of J1 and the +16.4 V to the Pin 2 (Heatsink) of U2, so the same connections were made in the new one. The board for the earlier one was remade to match the new one.  

The power jack is a 4-pin Amp C16 male connector (C016 20C003 100 12). The battery voltage is connected to its pin 1 and the battery ground to its pin 3. The plug in the cable is a 4-pin Amp C16 female connector (C016 20D003 100 10).
