LEAKAGE TESTThe AC leakage from any exposed metal part to earth
groundand from all exposed metal parts to any exposed metal
parthaving a return to chassis, must not exceed 0.5 mA
(500microamperes).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 touse these
instruments.
2. A battery-operated AC milliammeter. The Data Precision245
digital multimeter is suitable for this job.
3. Measuring the voltage drop across a resistor by means of aVOM
or battery-operated AC voltmeter. The “limit” indica-tion is 0.75
V, so analog meters must have an accurate low-voltage scale. The
Simpson 250 and Sanwa SH-63Trd areexamples of a passive VOMs that
are suitable. Nearly allbattery operated digital multimeters that
have a 2 V ACrange are suitable. (See Fig. A)
After correcting the original service problem, perform the
fol-lowing safety checks before releasing the set to the
customer:1. Check the area of your repair for unsoldered or
poorly-sol-
dered connections. Check the entire board surface for
soldersplashes 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
absolutelycertain that you have replaced all the insulators.
4. Look for unauthorized replacement parts, particularly
tran-sistors, that were installed during a previous repair.
Pointthem out to the customer and recommend their replacement.
5. Look for parts which, though functioning, show obvioussigns
of deterioration. Point them out to the customer andrecommend their
replacement.
6. Check the line cords for cracks and abrasion. Recommendthe
replacement of any such line cord to the customer.
7. Check the B+ and HV to see if they are specified values.Make
sure your instruments are accurate; be suspicious ofyour HV meter
if sets always have low HV.
8. Check the antenna terminals, metal trim, “metallized”knobs,
screws, and all other exposed metal parts for ACLeakage. Check
leakage as described right.

unless otherwise noted. (pF: µµF)
Capacitors without voltage indication are all 50 V.• Indication
of resistance, which does not have one for rating electrical
power, is as follows.
Pitch: 5 mmRating electrical power 1/4 W (CHIP : 1/10 W)
• All resistors are in ohms.• : nonflammable resistor.• :
fusible resistor.• : internal component.• : panel designation, and
adjustment for repair.• All variable and adjustable resistors have
characteristic curve B, unless
otherwise noted.• : earth-ground.• : earth-chassis.• When
replacing the part in below table, be sure to perform the
related
adjustment.• All voltages are in V.• Readings are taken with a
10 MΩ digital multimeter.• Readings are taken with a color-bar
signal input.• Voltage variations may be noted due to normal
production tolerances.• * : Can not be measured.• Circled numbers
are waveform references.• : B + bus.• : B – bus.• : Signal
