402®/802® II Controllers
The following part numbers used in the 402 and 802 II Controllers as listed inTable 1
have changed. If you are replacing parts on an older unit with the removable front panel
(see Figure 1), use the part list in the 402/802 II Controller service manual. Use the part
list in Table 2 for newer units that have a one piece chassis (see Figure 2). The old style
PCB with the heatsink mounted to the board will not fit in the new style chassis. The new
style PCB, with clip-on heatsinks, will fit into the old style chassis. Both PCBs are
functionally identical. Refer to the 402/802 II Controller service manual, part number
174785 for all disassembly/assembly and test procedures.
