1. Safety Related Components Warning

wComponents marked ! are critical to safe operation.Therefore, specified parts should be used in the case of

replacement.

[WARNHINWEIS][WARNHINWEIS][WARNHINWEIS][WARNHINWEIS][WARNHINWEIS]Les composants identifiés par la marque ! sontcritiques pour la sécurité.

spécifié.

2. Standardization of Parts

Some repair parts supplied by Sony differ from those

used for the unit. These are because of parts common-

ality and improvement.

Parts List has the present standardized repair parts.

3. Stock of Parts

Parts marked with “o” at SP (Supply Code) column of

the Spare Parts list may not be stocked. Therefore, the

delivery date will be delayed.

Items with no part number and no description are not

stocked because they are seldom required for routine

service.

SAFETY CHECK-OUT

After correcting the original service problem,

perform the following safety checks before

releasing the set to the customer :

Check the metal trim, “metallized” knobs,

screws, and all other exposed metal par ts for AC

leakage. Check leakage as described below.

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 3.5 mA. 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 5.25 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 operateddigital multimeters that have a 20 V AC range

are suitable. (See Fig. A)
