General Electric, or GE, developed the IC3600SCBE1 printed circuit board (PCB). This part is a component in the Mark I-II turbine control system. The MKI (Mark I) and MKII (Mark II) were the first two systems to be introduced in the Mark series.
The IC3600SCBE1 is a rectangular green PCB. Near the middle of the circuit board, there is one (1) large yellow capacitor. This capacitor is solid and contains its part number, 708A1, which is printed on the outside. This large capacitor contains a voltage of two-hundred (200) volts, which is labeled as 200V. Two resistors are situated directly above the capacitor. One of these resistors is located on the upper edge of the IC3600SCBE1. This resistor is large and brown in color. It features black, brown, gold, and yellow bands. The IC3600SCBE1 contains small metal components which help wires the circuit board into the larger system. The resistor is to those metal components with wires on either side. One (1) medium-sized resistor is positioned below the large resistor. The medium resistor is also colored brown and it features bands which are red, pink, yellow, and brown. The metal components also connect this medium resistor to the IC3600SCBE1. The IC3600SCBE1 has a long line of large metal prongs aligned on the right side of the circuit board. The IC3600SCBE1 is marked all over with labels in yellow print. The components located in the middle of the IC3600SCBE1 are marked with the letters A to F. The numbers ten (10) through fifty (50) are listed along the right side of the board by tens.
