Who know the voltage gain factor of this power amplifier ?
And which magazines have tested this power amp ?
I found only the review from German's vintage magazine HiFi-Vision 8/1992. Maybe one of the member can upload the review.

Hi, I have here an English review from HiFi News November 1992 which I have uploaded for you. This is the most technical detail on the amp I have been able to find. No circuit diagram or service manual though.

I also had encounter two monoblocks of this with 2 pairs of K1058/J162 output with massive trafo and heatsink. Burnt board and can't find reference schematics with some smd parts and not repair friendly construction especially board mounting of driver and output mosfet.
