Audio Amp Build

Finally getting around to building a chassis for my latest amp; its based on this design (http://www.tech-diy.com/LM4780_bridgedamp.htm) I had most of the parts kicking around; so I'm finally going to build a decent amp for my Mission V62 speakers.  Nothing too crazy +-30VDC Rails; 33000uF cap bank; running the LM4780 in bridged mode to keep distortion low.  Gives 120W RMS per channel while keeping distortion under 0.01% across the spectrum at full power(at least according to the guys at tech-diy.com)

I got the heatsinks and main chassis supports cut; I'm going to get some sheet metal cut and powdercoat it some fancy color.
