Many thanks for your quick reply Huntingdon

I'm now ordering the equipment and I've got one silly question:
Why do we put an for insulator if we want to transfer the heat to the heat sink and this by adding conductive heat paste?
or maybe I'm confused with the term insulator

Cheers

There are no silly questions...

An insulator is placed between the IC and the heatsink because the metal block in the TDA2616 is internally connected to pin 5, which is the -ve power supply. In a normal installation the heatsink will be at ground potential, and the insulator is thus required to avoid shorting the -ve supply to ground.

I have ordered my transformer 2A Secondary 48VA 12-0-12V and received a 3A as an upgrade I was told.
Is it still suitable for this Kit?

Besides I'm planning to cut a spare mains socket cable to figure 8 as my mains cable to my transformer is it ok?

More precisely it's a 72VA 12V 3A is it too much power?
or should I be happy about this upgrade?

The 72VA transformer will be fine. You're getting more transformer than you paid for, and with the price of copper as it is these days you can be happy.
