Default Please help with Thule Audio PA250B mkII amplifier

Hello Everyone,

Reading threads on Thule, I understood that support for multichannel amps is nearly non-existent, but I don't want to loose hope, yet.
My Thule Audio PA250B mkII amplifier has malfunctioned (left surround channel isn't working anymore and also left front channel isn't working when I switch to stereo). The specialist, who checked it claims the problem is in one of the chips. As I understood he disabled the left surround channel, because it kept burning and he suspects that this chip is to blame. I've found out that this is a custom resistor network made specially for Thule and no alternative can be found on the market. I've asked some 7 former distributors (including, and ). Unfortunately they don't have it. I'm totally lost now and don't know what to do.
Maybe somebody could give me an advice where to ask about the chip or a workaround solution or help to repair it. Maybe somebody has a contact of Anders Thule himself?
I'd be very grateful for any information on this.
I've attached pictures of the faulty chip.

Thank you and best regards,

P.S. also does anybody know where to find a service manual exactly for PA250 mkII, because I have both manuals for PA250 and PA350, of which the latter is similar to the schematics of my amp, but still not exact
