Hi Friends
I got this amplifier(Mafco M-601MP) from my friend who did a bit of repair but it's not clear what changed
I want someone to help me fix it.

Thanks

Look for reworked solder joints.
Read threads in car audio section to find out the equipment and methods required to test the amplifier.

Quais os testes que você já fez nele? Testou as tensões?

Hi
I think the parts I've identified are the pieces that have been opened
Now I do not know what pieces have been removed....

One is for fan control
And another part of the class output class D
