following safety checks before releasing the set to the customer:
1. Check the area of your repair for unsoldered or poorly-sol-
splashes and bridges.
certain that you have replaced all the insulators.
out to the customer and recommend their replacement.
mend their replacement.
Check leakage as described right.
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
Leakage current can be measured by any one of three methods.
1. A commercial leakage tester, such as the Simpson 229 or RCA
tion 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 bat-
tery operated digital multimeters that have a 2 V AC range
are suitable. (See Fig. A)
