This project came out well. The amp works great. I brought it to Madrigal to be tested and it didn't reach the specs that Tripath had but this may have been due to the equipment. The THD (total harmonic distortion) which should have been really low was at the best 3%. This may have been due to the chip that controls the EV board effecting the equipment. The output was 111 watts per channel compared to 150 watts that Tripath's spec says. This may have been due to a lower voltage on the varaible ac power supply. It may not have reached Tripath's specs but I think it sounds really good. I had it hooked up to the House Wrecker and ran it for a while and it had no problems moving the big fifteen. The circuits that we built to add on really didn't work as well as we had hoped. They worked but once it was turned up at all they made the speaker pop when the bass hit. I will be looking into this. I hope to get the bridging circuit to work right with no noise so that I can get more power. I would like to be able to run both of the fifteens in the House Wrecker. Before I was only running one speaker off one channel. I think with a little more work I will have it working as it should be.
