1. Check the area of your repair for unsoldered or poorly-soldered

connections.  Check the entire board surface for solder splashes
and bridges.

2. Check the interboard wiring to ensure that no wires are

“pinched” or contact high-wattage resistors.

3. Look for unauthorized replacement parts, particularly transistors,

that were installed during a previous repair.  Point them out to
the customer and recommend their replacement.

After correcting the original service problem, perform the following
safety checks before releasing the set to the customer:

4. Look for parts which, though functioning, show obvious signs

of deterioration.  Point them out to the customer and recommend
their replacement.

5. Check the B+ voltage to see it is at the values specified.

◆ MODE SWITCH (PROGRAM SWITCH) ASSEMBLY POINT

1) When installing the ass’y deck on the Main PCB, be sure to align the assembly point of mode switch.

 GEAR WORM

Fig. 3

FRAME

◆ HOW TO EJECT THE CASSETTE TAPE
    (If the tape is stuck in the unit)

1) Turn the Gear Worm 1 clockwise in the direction of arrow with a screwdriver. (See Fig. 2)
    (Other method ; Remove the screw of Motor Load Ass’y, Separate the Motor Load Ass’y)
2) When Slider S, T approachs the unloading position, rotate holder Clutch counterclockwise after inserting screwdriver in the frame’s bottom hole
    in order to wind the unwound tape. (Refer to Fig. 3)
    (If you rotate Gear Worm 1 continuously when tape is unwinding, you may cause tape contamination by grease and  tape damage. Be sure to
    wind the unwound tape with the unit in the horizontall position.)
3) Rotate Gear Worm 1 clockwise using a screwdriver until the mecha is in the eject state. Remove the tape. (Refer to Fig. 2)
