Or is that "makes music beautiful"
I'd been lusting after a Tripath-based amp for a while, and a 41hz one specifically. Being a DIY-er, I figured I should build one myself - though this was my first DIY audio project since building speaker boxes 15yrs ago.
Apart from a mix-up on the RIN and RFeedback resistors (resulting in a low gain) everything came together great. I'm powering it with a 19.6V laptop SMPS and have it running a pair of 6.5" 2-way Infinity bookshelf speakers.
As others have mentioned, the case was the hard part! I used a lot of locally-available parts (but ordered an ALPS Blue Velvet pot) so you'll probably recognize many parts. I was going for a bit of a retro look, and wanted to incorporate some wood, so this is what I came up with not having a workshop to fab anything anymore. (No comments about the spring terminals, please. I know, I know, but in this case they were convenient and since this is for on-the-road sorts of audio, I'm happy with them - till I replace them!)
Thanks to everyone on the forum (esp. V-Bro & Sparky) the existing messages helped me through the few questions I had!
