About the IC3600SHPB1
The IC3600SHPB1 is what is known as a 0-10 FLTR/FLTZ Single Shaft Auxiliary Card. The IC3600SHPB1 was made as a component in the Mark I-II series by General Electric or GE. The Mark I and Mark II were the initial series produced in the Speedtronic Mark line by GE.
A large metal plate is attached to the left border of the PCB. One (1) large grey knob is situated on the metal plate near the center. The words UNDER SPEED are printed on the plate above the large knob. This knob may be adjusted within a range of numbers from zero (0) to ten (10). Below this large knob, there are two (2) LEDs or light-emitting diodes. The diode on the top is labeled as FLTR and the lower diode is labeled as FLTZ. On the opposite side of the metal plate, the large grey knob is connected to the IC3600SHPB1 with white wires. At the top of the IC3600SHPB1, there are two (2) large rectangular black devices. One the bottom edge of the IC3600SHPB1, there is one (1) large silver capacitor and a few smaller silver capacitors. These capacitors are sitting vertically on the IC3600SHPB1. Several other capacitors which are solid yellow are situated on the lower half of the IC3600SHPB1. Many resistors which are patterned with colored bands are placed all over the IC3600SHPB1. A majority of the resistors are a light blue color that have bands that are red, blue, green, and yellow. The others are pink with bands that are black and red.
