Dreaming of a DIY 8W Class A amp designed by Nelson Pass?
I love building kits. This is a great sounding little amp. I’ve built 3 of these. First I built two to run as mono. But found that a single running in stereo was really enough and sounded just as good with an efficient set of speakers. So I sold one amp. Then after awhile, I wasn’t using the ACA amp and ended up selling that one too. But then I missed it, so I bought a third kit and built that one which gets switched into a second system. I pair it with a Schitt saga. I also have paired one with an Elekit 8500 preamp I built and have since sold. Ps. Elekit are great products, I’ve built four different amps from them. cheers k |
@dgarretson - you can test these Zerozone power supplies stock, but you can also upgrade the power cord and the fuse. In addition, I upgraded my DC output cables as well. I used a 5.5mm x 2.1mm DC plug from Digikey: https://www.digikey.com/product-detail/en/switchcraft-inc/767KS17/SC1389-ND/2238432 And 16awg UTP VH Audio cryo-treated OFC hookup cable w/ AirLok insulation below: https://www.vhaudio.com/wire.html#ofcairlok The results of the DC cable upgrade were significant. I kept the DC connector on the power supply side because it's hard to find the correct size replacement. I just de-soldered the existing cable and solder on my VH Audio wire. |
@dgarretson - What Furutech connectors did you use? I don't see any DC connectors made by Furutech. The best I have seen is the Oyaide ones below: https://www.vhaudio.com/connectors-rcaxlr.html#OyaideDC But they are gold-plated, which slows down and warms up the sound. I chose the switchcraft ones because of this. As far as wire, I prefer pure copper (my preference) because silver can be a little to fast/sterile for me. I can't imagine trying to solder 10-11awg wire to these tiny DC connectors! lol. |
