I measured 10 pin connector on  YTO (5086-7833) oscillator with digitalmultimeter after the analyser was switched -on.

pin nos.    standardsignal    obtained

 

Pin1     =  minus 15v    =   minus 15.02v

 

pin2     =  a gnd           =          -

 

pin3     =  a gnd           =          -

 

pin4     =  +5v             =  +5v

 

pin5     = maincoil+     =  +14.81v

 

pin6     = maincoil-      =  +9.63v

 

pin7     =   a gnd         =      -

 

pin8     =  +15v          =  +14.83v

 

pin9     = FM-signal     =   0.041v

 

pin10   = FM+signal    =   0.041v
