Thank you all.
I would like to do this test but I need to check about correct
procedure: would it be proper to solder a 3.9 zener diode with the -
end to the tuner's AGC pin and the + end to the tuner's ground.
I understand the idea is to clamp the voltage to 3.9; is this right?
I will wait for confirmation.
