If you want to learn please follow directions. measure your PSU first. red and black marks on green plastic not enough.
Is your DMM capable of displaying negative voltage reading? Reverse leads on your last pictured measurement. It should show “-“ a n front of voltage number.
If you don’t understand what you doing this exercise is pointless. Try to understand single vs dual rail first.
Let's try lol...
if you can't see me here anymore ... it's because I burned with the amp 😀
PSU marked V- G V+. amplifier B- G B+. make sure its connected V- to B- G to G V+ to B+. if that is correct go ahead power it up. you gonna be fine, just keep clear from powered up circuits.
And for God`s sake buy yourself a book, learn basics. Jumping to this hobby without basic understanding is to get frustrated with disappointment. I doubt you fried your board but it`s possible if polarity ever been reversed.
Hi Dani,
The power supply seems OK. Left if minus, mid is ground and right is positive.
For the amplifier board, scroll down a little and you can see the power connections ( WONDOM AA-AB32321 IRS2092 Module amplificateur stereo class D 2x125W 8Ohms - Audiophonics ).
No reaction of the amplifier with these connections?

Hi amigos, first : let me say THANKS for your help... That was my first double Rail PSU, unsually I do not use those kinds of power supply.
Here the final result, seems to work fine. I am still listening to my HD Audio music and I will let you know my feelings about the Wondom IRS2092
