I now must say that the AGC pin from the tuner is connected directly to
the pin of the I/C; no resistor is connected in series between the 2
pins.
However there is a couple of resistors off this line therefore in
parrallel. Is this still okai to do the test?

There is a risk of blowing up the IC. Disconnect the tuner pin and use a
variable power supply directly to the AGC pin of the tuner. Or use a 9V
battery with a 10k variable resistor.
