Mario, From the links and your description, I assume that you have an Amatuerradiokits case with the audio amplifier.
Yes I have.
If that is correct, then the data that I have shows a TA4225 (not a TA4425) audio amp IC as the audio amp. That is a 5 terminal device, not 3. That board is very cramped, so it could be that the silk screening is really pointing out the TA4225 5 pin socket and not the 3 holes that are close by.
Sorry for the confusion. The part has 5 terminals. That's true.l
Attached are the 2 pdf files that I have for the audio amp.
I saw this already in the documentation. On the first pdf there are 3 terminals shown. The top one is for the power. the middle is labed "A/IN" and the bottom terminal is labled "AGC V". Both Terminals do have 2 pins each. Where should I connect this pins of the 2 terminals?
My guess is that the 3 hole location is for the onboard "volume" control that is really a maximum volume control as the front panel volume control is used to adjust the volume in operation. You should have a blue 3 terminal variable resistor that goes into that location.
true

Please help me to get this AGC and the AMP connected.
