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 0.5 mA (500 microamperes).
Leakage 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 use 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” indication is 0.75 V, so
analog meters must have an accurate low-voltage scale. The Simpson 250
and Sanwa SH-63Trd are examples of a passive VOMs that are suitable.
Nearly all battery operated digital multimeters that have a 2 V 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. 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. 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 transistors, that

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

5. Look for parts which, though functioning, show obvious signs of

deterioration. Point them out to the customer and recommend 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 connector shell, metal trim, “metallized” knobs, screws, and

all other exposed metal parts for AC Leakage. Check leakage as de-
scribed right.
