Item as described and works well. You have to assemble it with the eight screws supplied which are quite small and fiddly however the heat sink was the most difficult bit because there were no instructions and it was not clear where it went. I managed to find some instructions on alibaba so it worked-out in the end. Note that I used a 12W power supply because I am not convinced that it is capable of 50W per channel. Even at this low power the sound it quite loud.

Megjött,ki kell próbálni. Köszönöm szépen!
