Many electrical and mechanical parts in television receivers have special safety related characteristics. These charac-

teristics are often not evident from visual inspection nor can the protection afforded by them necessarily be obtained by

using replacement components rated for higher voltage, wattage, etc.

Replacement parts which have special safety characteristics are identified in this service manual.

Electrical components having such features are identified by shading on the schematic diagram and parts list of this

service manual, and by marking on the supplementary sheet for this chassis to be issued subsequently. Therefore,

the replacement for any safety part should be identical in value and characteristics.

The PWBs used in the V33+ and V33Y chassis are constructed using Lead-Free solder. When

Pb Solder

servicing use only recommended Lead-Free solder (refer to page 38).
