Thanks so much for this instructable! Thanks for documenting it, it sounds great! At the end I decided to make the power source as 2 dc sources connected in series as in http://www.markhennessy.co.uk/articles/power_suppl... the rest is exactly the same :)I also made use of a kind of pcb for the components, reinforcing some of the connections just in case there would be too much intensity. Sound is very nice and can power up my speakers with no problem at all. For the heatsink I used a piece of metal and attached on top a couple of spare small heatsinks that I had around. I just need to change the potentiometer, it turned out to be noisy for a particular angle. I add couple of pictures. Thanks a lot once again!
