Yes, D3 must be inverted as you can see in Apex components PCB.

A nasty PCB, without numbered parts ... could be better. However, the schematic should be in correlation with PCB.

A nicer PCB is the one posted by @student II although the distance between PCB tracks should be checked there!!!

Regarding the schematic, you would need a resistor or jumper between SGND and GND, very useful especially if we want to test only PCB amplifier.

Fuses should protect all the amplifier. I'm saying this because in my experience I had customers who have dropped cognac inside the amplifier - through the air vents of the casing - and so there was a short circuit in the VAS circuit. The lack of fuses to interrupt this was useful because it limited the damage. So you never know who you sell your amplifier !!! There are rare cases, but they can exist!
 
podrias compartirme por favor el pdf, porque yo lo arme y no me funciono, me pregunto en que me habre equivocado

Ola yo poderia hablar castelhano pero esto es un english forum, so you should speak in english. I gona send tou you information about B500P.

Javys, debes escribir en Inglés o los Miembros del Foro no pueden ayudarte.
Es un Foro Internacional, hay miembros de todos los países e idiomas, han convenido en usar Inglés como idioma común.
Si no sabes Inglés usa Google Traductor o algún otro.
No es perfecto pero peor es nada. :D

Note to Moderators: don´t waste time translating, this is only a suggestion for Javys to use Google Translate or something, both ways :)

EDIT: thanks Kandimba, muito obrigado :)

As you can see in Post #3432, you have VI limiter as well as Prot. detection to activate PSU 7 Protection, and you have more: Led indication for ON, Signal and overload.
