I’ve decided to embark once again on an amplifier project. This one will go a little bit different than the last electronics project which was strictly a headphone amplifier. This one is a Class-T amplifier, based on a tripath chip. It comes in kit form, with a PCB, components, and jacks. The kit (an Amp6 Basic) was from 41hz.com audio, and I’ve already had the pleasure of building one kit (and hearing it) from my good friend Woody. It sounds incredible for its price and size. It’s slightly cheaper and better quality than the Sonic Impact T-amps which are sold commercially. It runs from a 12V power supply. Note I had to cut of the original tip from the PS and reattach a new one as the old tip was not correctly sized for the T-amp’s DC input jack.
Without further ado, I am providing pictures of my build as I get it completed. The eventual goal is to build and complete the kit, enclose the kit in a nice hardwood enclosure, and then build a set of full range driver speakers to listen to the amp. The speakers will also be custom built. More on that later (it’s a secret for now). Excuse the fuzzy pictures, as my camera is not able to do macro shots very well.
Update (June 10th, 2007): I’ve added the rest of the components, and run initial tests of the amp. It sounds fantastic, especially with my Athena speakers. For 10 watts, I have a pretty awesome sounding amp with good clarity and midrange. I also added a SPST switch for the sleep function (replacing the jumper directly on the board) and a bright blue LED. I’m happy with it so far. Now on to the enclosure for the amp…..
Update (June 16th, 2007): I’ve started (and basically finished) the Amp6 enclosure. Soft maple, walnut strips, and some sandeply plywood that I had left over. All 1/2″ materials. I’ve basically got the shell done and all the holes machined for the various connections. I coated the exterior with Tried and True Varnish Oil and I’ll be adding a coat or two of paste wax. The cover screws on using #6 square drive screws.
Update (June 17th, 2007): I’m done! It’s working, and sounds great. Looks good in its enclosure. Phew. Now on to the speakers.
