SAFETY CHECK-OUT
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.

 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 approached 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 in state of unwinding, you may cause tape contamination by grease and tape damage. Be
sure to wind the unwound tape in the state of set horizontally.)
3) Rotate Gear Worm 1 clockwise using screwdriver again up to the state of eject mode and then pick out the tape. (Refer to Fig. 2)
