MODEL TYPE IDENTIFICATION
In this set, the routing of speaker lead wires and the boards have been changed in the midway of production, and the set is grouped into the following four types depending on the specifications. TYPE A: Original model. TYPE B: To the original model, the routing of speaker lead wires is changed. TYPE C: To the type B, the print patterns of board are changed. TYPE D: To the type C, the shapes of boards are changed. · Model Type Discrimination Identify each type from the part number printed on each board by referring to the following table. Also, each board is common to type A and type B, but routing of speaker lead wires is different. For details of different places, refer to "6. Diagrams 6-10. Printed Wiring Boards MAIN/POWER SUPPLY Section (Type A, B) " (page 42, location A-1 and B-1).

*1) For the LED board, only the lower five digits of part number is printed. · Precaution on Replacing the Boards The supplied boards are all type D, and therefore if the board is replaced, use the board of type D only whichever model is serviced. However, on the type D model, the number of pins of connectors that connect MAIN board to CD board, and MAIN board to POWER board has been changed, and accordingly the type D is not interchangeable with type A, B, and C respectively. Therefore, if even one of MAIN, CD, and POWER boards is replaced, replace all three boards simultaneously.
