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.

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. MODEL IDENTIFICATION  MODEL NO.
