Default Mini Stereo Amp with Bluethooth build

just decide to build a small amplifier for my old Morel MLP305,
my main goal was to achieve quality, cheap and reliable amplifier.

Parts List:
Chassis WA5 from eBay. (Link)
Bluethooth Receiver & Dac from Ali (Link)
2.4G Antenna from eBay (Link)
Main transformer from eBay (Link)
Small YHDC transformer for Trigger and BT from eBay (Link)
Signal trigger Module from eBay (Link)
Amp modules from eBay - SMD version (Link)
Mini Speaker protection board (Link)
Volume Preamp board from eBay (Link)
PSU board & AC to DC converter bought from Motronix directly.

the build took only 1 day and the sound really surprise me, its so Natural and Detailed, much better than my old Luxman RV387.
