SXA 100 I'm looking for a diagram

Hello everyone.
I'm looking for a reference schematic to better understand this amplifier.
The problem is that there's no volume control (it's set to high) and it's very noisy.

It would be something like this:

That's more of an idea than an amplifier schematic. But the output stage is common emitter, and has voltage gain.

This amplifier is the strangest thing to me.
I've searched the web for a similar schematic and can't find anything like it.

What I found, but not the same, is this:

The Transnova amplifiers, like Hafler, have such an output stage.
