After correcting the original service problem, perfom the follow-

ing safety checks before releasing the set to the customer:

l. Check the area of your repair for unsoldered or poorly-sol-

dered 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. Check that all control knobs, shields, covers, ground straps,

and mounting hardware have been replaced. Be absolutely

certain that you have replaced all the insulators.

4. Look for unauthorized replacement parts, particularly tran-

sistors, that were installed during a previous repair. Point them

out to the customer and recommend their replacement.

5. Look for parts which, through functioning, show obvious

signs of deterioration. Point them out to the customer and

recom mend their replacement.

6. Check the line cords for cracks and abrasion. Recommend

the replacement of any such line cord to the customer.

7. Check the condition of the monopole antenna if any). Make

sure the end is not broken off, and has the plastic cap on it.

Point out the danger of impalement on a broken antenna to

the customer, and recommend the antenna’s replacement.

8. Check the B+ and HV to see they are at the values specified.

Make sure your instruments are accurate;be suspicious of

your HV meter if sets always have low HV.

9. Check the antenna temminals, metal trim, “metallized” knobs,

screws, and all other exposed metal parts for AC leakage.

Check leakage as described below.

/($.$*(7(67

The AC leakage from any exposed metal part 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) . Leak-

age current can be measured by any one of three methods.

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

RCA WT-540A. Follow the manufacturers’ instructions to

usc these instruments.

2. A battery-operated AC milliammeter. 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” indica-

tion is 0.75V, so analog meters must have an accurate low-

voltage scale. The Simpson 250 and Sanwa SH-63Trd are

examples of a passive VOM that is suitable. NearIy all bat-

tery operated digital multimeters that have a 2V AC range

are suitable. See Fig. A)

+2:72),1'$*22'($57+*5281'

A cold-water pipe is guaranteed earth ground;the cover-plate re-

taining screw on most AC outlet boxes is also at earth ground. If

the retaining screw is to be used as your earth-ground, verify that it

is at ground by measuring the resistance between it and a cold-

water pipe with an ohmmeter. The reading should be zero ohms. If

a cold-water pipe is not accessible, connect a 60-l00 watts trouble

light not a neon lamp) between the hot side of the receptacle and

the retaining screw. Try both slots, if necessary, to locate the hot

side of the line, the lamp should light at normal brilliance if the

screw is at ground potential. See Fig. B)
