10、AN 60 SERVICE NOTES 1.HORN REPLACEMENT requires speaker removal in order to access horn wiring. If wire ties, clamps, etc. are removed for ease of connecting/disconnecting horn wires, these must be replaced to prevent buzzing at higher power levels. 2.CHASSIS REMOVAL is accomplished by first removin

11、g six (4) screws from the top, and one (1) screw from each side of the cabinet; then slide the chassis toward the rear just far enough to provide access to the speaker wiring. Note: The speaker wires are tied to a chassis lance, and must be re- tied after servicing (for safety compliance). Locate th

12、e speaker wires (white goes to P1, black goes to P2 of the power-amp board) and disconnect them. It should be noted that the speaker wires have been glued in place inside the speaker baffle (for sound quality reasons), if this is disturbed during disassembly, it should be restored by removing the sp

13、eaker, and working through the speaker hole; leave sufficient slack to allow reassembly of the speaker leads to the chassis. For reference, the red wires from the transformer go to P3 & P5. The red/yellow wire goes to P4. PARTS LIST NOTE: SHADED ITEMS ARE FOR REFERENCE ONLY PRINTED CIRCUIT BOARD ASS
