Nelson Pass ACA Stereo

Nelson Pass’ ACA is the most popular DIY project for a low budget Class A power amp.
We described it extensively in a previous video that you can find here:

In this new video we will use two units, connected in XLR, in order to doubling the power. We also got the opportunity to test a linear power supply, now as a prototype, which definitely improves performance. In short, ACA across the board, and this to encourage all our followers who love DIY to try at making it.
