Chapter 12 Schematics, Board Layouts, and Parts Lists
This chapter contains the schematics, board layouts, and parts lists 
for the SSE 5000 radio. Use them in conjunction with the theory of 
operation and the troubleshooting procedures, charts, and waveforms 
to isolate a problem to the component level.
The following tables list the pages where the schematics, board 
layouts and parts lists for the SSE 5000 radio are found.
