SAFETY CHECK-OUT
(US model only)
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.
8. 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 cord 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 terminals, metal trim, “metallized”
knobs, screws, and all other exposed metal parts for
AC leakage. Check leakage as described below.

== Earth Ground
Fig. A. Using an AC voltmeter to check AC leakage.
LEAKAGE TEST
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). 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.
8. 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 low-voltage scale. The Simpson 250 and
Sanwa SH63Trd 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)
HOW TO FIND A GOOD EARTH GROUND
A cold-water pipe is guaranteed earth ground; the cover-
plate retaining 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 60-100 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.
