GND  
Circuit diagram  
PRE GND  
GND for the HEAD AMP.  
Use this terminal for the pin 17 to pin 21 GND  
connections to improve the noise characteristics.  
Connect this pin to the main GND (pin 16).  
19  
PRE IN ch2  
Inputl for the playback amplifier (ch2).  
The low-frequency cutoff characteristics can be  
adjusted with the value of the input coupling  
capacitor.  
The frequency characteristics can be adjusted so  
that it is flat with the L value of the rotary  
transformer, and the external capacitor C (100pF  
etc.).  
REC: 0V  
PB: 0.7V
