8. This circuit diagram covers a basic or rep-

resentative chassis only. There may be
some components or partial circuit differ-
ences between the actual chassis and
the circuit diagram.

9. 

Diode 1S1555 may be replaced with
1S2473, 1S2076 or DS472 unless oth-
erwise noted.

■ 

Transistor 2SC536(Q,R,S),
2SC1740(Q,R,S), 2SC945A(Q,R,P) or
2SC1815(G,O,Y) unless otherwise
noted.

Transistor 2SA608(E,F) may be
replaced with 2SA933(Q,R),
2SA564(QA,RA), or 2SA1015(O,Y)
unless otherwise noted.
