SCHEMATIC DIAGRAM (TUNER)

* All voltage are measured with a 10M

Ω

/V DC electric volt meter.

* Components having special characteristics are marked 

Z

and

must be replaced with parts having specifications equal to those
originally installed.

* Schematic diagram is subject to change without notice.

Each voltage represents the voltage when receiving FM (stereo) signal and the voltage in the parentheses (

) is the voltage when receiving AM signal.
