SAFETY CHECK-OUT
After correcting the original service problem, perform the following
safety check 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
recommend their replacement.
5. Check the B+ voltage to see it is at the values specified.
1. Check the area of your repair for unsoldered or poorly-sol-
dered connections. Check the entire board surface for sol-
der 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 tran-
sistors, that were installed during a previous repair. Point
them out to the customer and recommend their replacement.
