SAFETY CHECK-OUT
1. Check the area of your repair for unsoldered or poorly-sol-
dered 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.
3. Look for unauthorized replacement parts, particularly transis-
tors, that were installed during a previous repair.  Point them
out to the customer and recommend their replacement.
After correcting the original service problem, perform the following
safety checks before releasing the set to the customer:
4. Look for parts which, though functioning, show obvious signs
of deterioration.  Point them out to the customer and recom-
mend their replacement.
5. Check the B+ voltage to see it is at the values specified.
