. Some printed circuit boards are not supplied as the assembled.
To separate these in this service manual, the stock Nos are not in-
dicated at the ends of the board names. However, the individual parts
on the circuit boards are provided by orders.

. Since some of capacitors and resistors are omitted from parts lists
In this service manual, refer to the Common Parts List for capacitors

& resistors, which was issued on February 1983.
