HTS 9800 W amp broken

Please help,
I own HTS 9800W and it stoped working
I bought this home theater in Croatia (Rijeka) where I live

the official Philips dealer servise for Croatia told me
that they know how to fix it but they cant order the parts

so please would you be so kind and help me where i can find
this PHILIPS part No: 313911857981 amplifier

thank you for your time

b.reg

I'm afraid that if the authorized Philips dealer can't get hold of it, it will be quite difficult to get it somewhere else. Maybe try to look for a second hand HTS9800 being sold for spare parts only?
