ADAM Active Studio Monitor schematic diagrams help

Gentlemen, again, whoever needs a manual has to send me a private message.
This should contain his e-address in the first place.

Repair success with errors unknown before should be reported here, thanks.

Hi, I can't send PM. Could you please send me Adam P33 schematic or service manual? Someone did a terrible job, I need to fix it. Thanks.

Hello,

I have a problem with one of my P11 box. it show very quickly the over red light and sounds a little bit saturated at low volume too. I take measures in main power supply capacitors and they show 39-40v each and don't go down if I up the volume. any help??

thanks in advance,
Antonio.
 
I have a pair of original S3-A's, where one of the two speakers outputs a really loud buzzing sound (max volume, and you can see the woofers retracting!) when activating them. This doesn't happen every time when powering on, but only periodically.
By quickly power cycling the speaker, I can get past this buzz. And once they are powered on without the buzz, they stay that way until powered off.
Any ideas where to look to solve this?

Many thanks!
