I'm ready to start on the Aleph-X DIY amp. I bought 3 stereo sets of circuit boards during the group buy at diyaudio.com and enough output FETs for all of them, even for the higher power version (app 80W/ch). I also have the appropriate torroid transformers. The rest of the parts will be ordered from Mouser when the actual build takes place. I'm looking for someone with metalworking experience and access to the right tools to make nice looking enclosures. To help getting started I can get some AutoCAD drawings done at work. Here is the deal, I'll supply working electronics for the three stereo amps (including power supplies), you make three enclosures and get to keep one complete amp. The cost of parts for all the enclosures should end up being less than or comparable to the cost of the guts for one amp. Suitable torroids alone are over $100.00/piece. The boards, fets, caps, resistors and other parts run close to $100.00 per amp as well. Each amp will need heatsinks. Their size will depend on how much power will the amp be biased for and whether we use 4 or 8 FETs per channel. I have some heatsinks for one of the amps. Again, I would like to end up with nice looking, presentable amps and not some rough-edged, square boxes. I'm not looking to steal design ideas, but the pic below shows a really nice DIY amp effort.A gallery of DIY Pass related projects: For folks unfamilliar with Aleph-X, the design is based on a super symmetry patent by Nelson Pass as used in his X series amps (starting at $3000.00 or so) and is a hot-running class-A design. The circuit is confirmed to be working with excellent results by people at diyaudio.com who participated in the group buy and finished their amps already. There are many threads about it on that forum. The project, as a DIY effort has the blessing of Nelson Pass himself. I live in Central PA and would like to collaborate with someone reasonably close. If interrested, drop me an email: groups at thuneau dot com.
