Many electrical and mechanical parts in television receivers have special safety related characteristics. These char-
acteristics are often not evident from visual inspection nor can the protection afforded by them necessarily be ob-
tained by using replacement components rated for higher voltage, wattage, etc.
Replacement parts which have special safety characteristics are identified on the schematic diagrams and parts list
of this service manual. The replacement for any safety critical part should be identical in value and character-
istics.
The PWBs used in this chassis are constructed using Lead-Free Solder. When servicing use
only recommended Lead-Free Solder. Refer to the section "Using Lead Free Solder."
