                    l   CCD-FX73OV is based on model CCD-FX430 (CCD-R(430/FX435/FX53O/FX630 SERVICE MANUAL).
                        [Main differences]
                        1. LCD screen addition (SD-14, PD-53 boards addition).
                        2. Speaker addition.
                        3. REC switch addition on control switch block (FK).
                        4. FADER switch addition on control switch block (CK).
                        5. Boards are changed.




                             The printed wiring board and schematic diagram for the AU-175 board and MA-209 board are not
                             shown because basically they are identical to the CCD-FX43O's AU-1 57 board and MA-l 97 board.
                    . In this service manual, only the differences from CCD-FX430 is mentioned.
                      When servicing, see the CCD-FX430/FX435/FX53O/FX630 service manual (9-973-530-l 1) with this.
