ETON 120VV Integrated Amp - Schematic wanted

[tiefbassuebertr]

ETON is the brand name for the German abbreviation "LPG" (Lautsprecher-Produktions-Gesellschaft mbH). The hifi loudspeaker range is very good known. But not the amplifier range. From this amlifier model I have never heard before.

A customer ask me, how expensive it is to create an outdoor power supply with ultimate dynamic behaviour while listening sessions of difficult music material.

For carried out a cost estimate therefore a schematic is very helpful. Who can post it?
Thank you for your efforts in advance.

BTW - about the ebay item No 120852577630 you will find an auction of this amp together with the Thorens CD Player "TCD 2000"
