The amplifier is assembled on a TDA7262 chip, the power in stereo version is 35 Watt, and in mono version it is 80 Watt.

Here is the assembled amplifier

Scheme:

stereo option

bridge version

I bought the case at a radio store, took a transformer from a broken music center, a cooler and a radiator from an old computer.

All assembled

1.there is no need for such a radiator.
2. If configured correctly, the microcircuit will heat up much less!
3.do not spoil computer hardware!
4. Why is it so powerful? The speaker on which it stands will not draw 35 watts, and with a power of 10 watts you will not be able to sit in the room.

There are these stores called radio parts or something like that. Keyword "Radio". They have similar microcircuits.
