TS-10 MECHANISM

— 2 —

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.

◆ HOW TO EJECT THE CASSETTE TAPE
    (If the unit does not operate on condition that tape is inserted into housing ass’y)

1) Turn the Gear Worm 1 clockwise in the direction of arrow with screw driver.. (See Fig. 2)
    (Other method ; Remove the screw of Motor Load Ass’y, Separate the Motor Load Ass’y)
2) When Slider S, T are approached in the position of unloading, rotate holder Clutch counterclockwise after inserting screw driver in the
    hole of frame’s bottom in order to wind the unwiunded tape. (Refer to Fig. 3)
    (If you rotate Gear Worm 1 continuously when tape is in state of unwinding, you may cause a tape contamination by grease and
    tape damage. Be sure to wind the unwiunded tape in the state of set horizontally.)
3) Rotate Gear Worm 1 clockwise using screw driver again up to the state of eject mode and then pick out the tape. (Refer to Fig. 2)
