I built my Nelson Pass A40
version in 2002, and I am very pleased with it. You can find much more
information on Nelson
Pass's DIY website under legacy amplifier projects (the design is
actually from 1978!). Below you can see some pictures of my design (click on the picture to enlarge it):

The 8 output transistors are mounted on 8 independent heatsink. My
heatsinks (1 K/W) are a little bit to small, so I have to use forced
cooling! |
