NOTES:
¢ The circuit shown in Be
on the conductor indicates printed circuit on the
back side of the printed circuit board.
© The circuit shown in |)
on the conductor indicates printed circuit on the
front side of the circuit board, which is put the mechanism unit.
© Components on back of P.B are identified by black symbols.
© Components on front of P.B are identified by blue symbols.
e The symbols (@) snown in the circuit board indicate connection points
between conductors on the front side and back side of the circuit board.
© Voltage values shown in [___] are measured values at the front pattern side
of the printed circuit board.
° Values indicates in [___] are DC voltage betwdeen the chassis and electrical
parts.
¢ All voltage values shown in circuitry are under nosignal condition and
playback mode with volume control at minimum position.
For measurement, use VTVM.
e(
)... Voltage value at IN (dbx switch) mode.
¢ This circuit board diagram may be modified at any time
with the development of new technology.
