Nelson Pass Aleph Clone by Gia

Nelson Pass is one of the most ingenious living designers. In addition to a large production of electronics under his own name, he has always kept the DIY channel very much alive, with a site even founded shortly after the birth of the web where he has always published very interesting articles and kits. The Aleph project grew out of two class-A power amp models from the 1990s that were quite successful; they were called Aleph 3 and Aleph 5 (30 and 50 W into 8 ohms, respectively). After a few years Pass published the schematics free of intellectual rights, and because of this they have become among the most cloned amplifiers ever. Many versions of this design can be found on Aliexpress, as well as much literature on the net. The design of the power amp that Gia has made, stems from the use of 4 low-cost Aleph 3 kits, which then for various needs became almost Aleph 5s, adopting 6 Mosfets instead of 4, but at a slightly lower supply voltage than Aleph 5. The power amp is then equipped with 4 identical amplifier sections, so that it is possible to use with speakers set up bi-wiring two sections for each speaker. In short, a customization in so many ways, which took a good 6 years of gestation for a publication-worthy result. 00.00 teaser 02.23 Description. 12.50 Technical analysis 20.48 Listening and conclusion
