About the IC3600VANA1
The IC3600VANA1 is a PCB component for GE’s Mark I and Mark II series. The MKI and MKII were the first of the gas/steam management systems that GE released in the Speedtronic line. Both of these series are now obsolete and are no longer supported by General Electric.
The IC3600VANA1 is built with eleven integrated circuits. This includes seven Motorola 7349-46 8411 circuits, and one each of their circuits marked 7349-46 8343, 7349-36 8422A, 7349-10 8323, and 7349-10 8448. These circuits are placed on the board in two parallel lines of four, with one line bisected by a perpendicular line of three.
The IC3600VANA1 has twelve transistors. These are marked Q1, Q2, or Q3. The transistors are placed on the board in four groups of three. The board has five ceramic capacitors and eight fixed vacuum capacitors. It is designed with two types of diodes, most of which carry the designator of “CR.” The board uses both metal film and carbon composite capacitors of varying capacitance. Many of these resistors carry the same designator; for example, there is more than one “R22” located on the board.
The board of the IC3600VANA1 is drilled in two corners. Right-angled metal pins populate both long edges, with one edge completely populated by these pins and the other having five pins equally spaced. The full line of pins functions as a communication device. The individual pins are marked as TJ1 through TJ5. The board is marked with the codes 006/09, 002/05, 003/06 and 68A944111.
