LM 3886 chip amplifier project

After several weeks of planning and acquiring components &amp amp parts,i finally got down to constructing a chip amp (gain clone) 50 RMS in to 8 ohms.. The amp uses the National Semiconductor LM3886 chip with printed circuit boards purchased locally. This is a simple chassis using 4 aluminum panels on top , back, bottom and 2 heat sinks on the sides. Front panel is 6mm thick. Amp was completed few months back, helped by my friend Sreekanth, without him i would not have completed this project. It has done about 80 + hours of burnt in, it sounds pretty good, will be upgraded with few more power capacitors for better low's after some time.
