Default ADAM Active Studio Monitor schematic diagrams help

Gentlemen,

in my workshop I have these active S1A "Professional Studio Monitor" loudspeakers for repair.
The amplifier is defective.

A diagram of this module would be useful. It is made by Hypex of the Netherlands,
no designation on it but date 10 Jul 2003. It carries a vast number of NE5332 ops
and two TDA7294 power amps, one LM339 and one TL074 are also visible. Should
be manageable to repair, but all traces and joints are very small - doesn't help my eyes.

The Adam company which is in my home town Berlin says that they don't have any
documentation and can not repair it. Since many of these were sold it would be good
to have them fixed in the true sense of sustainability. I suspect that other people have
problems with the amps also.

I understand that the head of R&D of Hypex is also around in this forum. Will he be
willing to assist?

Any help is highly appreciated, thanks.

EDIT: Diagram for S1A is in post 10.
Diagram for ADAM P33 (UCD-Version) is too large, I can send it by email.
Schematic for ADAM P7 is in post 12

Just ask Hypex for documentation. Jan Peter van Amerongen is your man.

Good luck

No, I do not know their answer.. I get the impression you have not even tried, but maybe I am wrong here.

This is the reply that I received from Hypex:
"Sorry, we cannot help you with this. We don't supply replacement components nor can we supply the schematics."
Now you'r my man ..

Hope it will help.

Sorry, it seems to be completely different. Does this have any name or known use?
But maybe we can start a Hypex diagram thread this way ..
