SAFETY CHECK-OUT
After correcting the original service problem,
perform the following safety check before releasing
the set to the customer:
Check the antenna terminals, metal trim, ‘“‘metallized”’
knobs, screws, and all other exposed metal parts for
AC leakage. Check leakage as described below.
LEAKAGE TEST
The AC leakage from any exposed meta! 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-S540A. Follow the
manufacturers’ instructions to use these instru-
ments.
tro
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 volt-
meter. 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 VOM that
is suitable. Nearly all battery operated digital
multimeters that have a 2V AC range are
suitable. (See Fig. A)

1. Demagnetize the record/playback and erase head with a head
demagnetizer.
2. Do not use a magnetized screwdriver for the adjustments.
3. After the adjustments, apply suitable locking compound to the
parts adjusted.
4. The adjustments should be performed with the rated power
supply voltage unless otherwise noted.
5. The adjustments should be performed in the order given in this
service manual. (Asa general rule, playback circuit adjustment
should be completed before performing recording circuit adjust-
ment.)
6. The adjustments should be performed for both L-CH and R-CH.
@ Switches and controls should be set as follows unless otherwise
specified.
DOLBY NR switch: OFF
TAPE SELECT switch: TYPE I (NORMAL)
e Standard Record:
Deliver the standard input signal level to the input jack
and set the REC LEVEL control to obtain the standard

ELECTRICAL PARTS LIST
e Due to standardization, replacements in the parts
list may be different from the parts specified in
the diagrams or the components used on the set.
@e items marked “x” are not stocked since they
are seldom required for routine service.
Some
delay should be anticipated when ordering these
items.
e If there are two or more same circuits in a set
such as a stereophonic machine, only typical
circuit parts may be indicated and capacitors and
resistors in other same circuits may be omitted.
