Thanks again Piero.

OK, make some measures.
With a VTVM or other *high* impedance voltmeter, make a reading at
juncton between R43 and C97 ( 4uF ) and chassis ground.
Must be approximately *minus* 3-4 volt.
That's the foot of the AVC chain and surely 3-4 Volts is *much* too low. I
get 27-30, which would be expected with a total current of 110 mA and a
total AVC chain of 275 Ohms.
Again, make a measure at junction between pot R46 pin 3 with R55 and
chassis.
Must be approximately *minus* 0,3-0,4 volt.
There is no pot R46. Do you mean RV3. Which do you mean by 'pin 3'
Cheers
Alan
