[Premium-Rx] AEG TELEFUNKEN ES1700 PRESELECTOR

[Pat1McA--- via Premium-Rx]

Greeting to List Members,
 
I am still looking for a circuit diagram of the ES1700, 52.1831.000.00,  
plug in Preselector for the E1700 and earlier E1800 HF Receivers.
 
Basically I want to disable the continuous running of the unit and provide  
a front panel enabled "Bypass" function so that when in "Bypass" mode the  
unit is lies dormant.
 
The later model ES150/2 does this but is far more complicated and is  
really an amazing "true work of AEG art".
 
Any assistance will be gratefully received. Thanks. Please reply  offline.
