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, par-ticularly
transistors, that were installed during a previous repair.
Point them out to the customer and recommend their
replacement.

4.

Look for parts which, through functioning, show obvious
signs of deterioration.  Point them out to the customer and
recommend their replace-ment.

5.

Check the line cord for cracks and abrasion.
Recommend the replacement of any such line cord to the
customer.

6.

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

6.

Check the antenna terminals, metal trim, “metallized”
knobs, screws, and all other exposed metal parts for AC
leakage.
Check leakage as described below.

The AC leakage form any exposed metal parts to earth ground
and from all exposed metal parts to any exposed metal part
having a return to chassis, must not exceed 0.5mA (500
microampers).
Leakage current can be measured by any one of three methods.

1.  A commercial leakage tester, such as Simpson 229 or RCA

WT-540A.  Follow the manufactures' instructions to use these
instruments.

2.  A battery operated AC milliammerter.  The Data Precision

245 digital multimeter is suitable for this job.

3.  Measuring the voltage drop across a resistor by means of a

VOM or battery-operated AC voltmeter. The “limit”
indication is 0.75V, so analog meters must have an accurate
lowvoltage scale.  The Simpson 250 and Sanwa SH-63Trd are
examples of a passive VOM that is suitable. Nearly all battery
operated digital multimeters that have a 2V AC range are
suitable. (See Fig. A)

After correcting the original service problem, perform the following 

safety checks before releasing the set to the customer.

1) Turn the Gear Worm Œ 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 Œ continuously when tape is in state of unwinding, you may cause a tape contamination by grease and
