2. 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.

3. 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.
