I should add that this (ACA) amp sounds wonderful. I have it powered with a 24v Meanwell power supply and it's hooked up to my Fusion-12 Tempest speakers and there is plenty power to spare. Also had it hooked up to my Nola clones and it is at home with those as well. I am currently running it from the pre-outs of my old Denon AVR for the bass management capability for the subs I use along with all of this stuff.

Very nice amp, indeed. Hat's off to Nelson Pass for sharing this. I had a great time building it and will certainly use it from here on out.

Default Mystery from 2008/9

I dug this out of my junk box but don't remember what it was. It's dual rail (+/- 9V), the caps are 10uF and the jfets are 2SJ108GR - pair of them per side. It's definitely not JFET BOZ but I can't remember what it was.

Maybe MPMarino or Dennis might remember but I'm certain it's from NP's brain.20180418_101745.jpg

Default SONY JFET 2

Hi,

Not as good a build as some but here it is anyway, very nice sound, also attached is the previous amplifier which is a sort of Nakamichi PA7 lite, so I guess it almost earns a place in a NP build picture. Compared to the class A bipolar, I guess I prefer it, I can listen to both but the class A is a little bit more "hi-fi" sounding, The JFET has a little bit more "boogie factor", "funk", "je ne sais Pass"?
