Default Schematics ??

hi all I have doubts why diagrams removed
if all this, now this amplifier with sigma delta modulator is basically the work of international rectifier IRAUD1 and pag.IRF is available in this forum is to discuss and learn and then teach because it removed the schematics and PCB artwork? ?
greetings to all ...if the moderator permits desire iraud1 put the diagram and leave here as a reference in fact heard super good

I've cobbled together a PSU/modulator board to go along with the power module boards.

It may not look too impressive but the seemingly long traces only handle TTL DC signals (enable/mute) so it shouldent be an issue.

This module uses a LM393 and is thus designed to be used with two power modules to form a full stereo amplifier, however i am not sure this will work as the two halves of the LM393 may interfer with each other, causing problems such as noise.
