Boards designed for mounting active component directly to heatsinks share a common universal mounting specification so you can tap your holes once and then re-use those holes for future projects, very handy if you'd like to experiment with several designs on a single chassis!
Please view the Burning Amplifier Configuration Guide to choose the appropriate PCBs for your your desired Burning Amplifier.
These boards along with the with your components and the P-BAGS-1V20 gain stage, then add your own power supply, chassis and heat sinks to complete the BA-2 amplifier in the 3 output pair per channel configuration recommended by Nelson Pass.

I've built it with 32V rail and 0.47ohm source resistors this does produce a lot of heat. Make sure you use big heat sinks with this combo. This amp sounds really good with ACP+ or Wayne's 2018 Linestage, clean, detailed and musical. It has no issue driving a pair of Boland Accoustic BTX180 made by Peter Boland of NZ. These are 4 ohm demanding speakers but the amp drives them effortlessly.
quality sound, this preamp is a highly recommended upgrade with my F5 turbo amp and the wilson watt puppy
Simple project, magnanimous sound!
Excellent PSU is a must. The PSU for the Bride of Son of Zen is adequate and sounds great at +-28 Vdc, but I opted for a Sigma 22 design at +-30 Vdc.
Board from diyaudio store is excellent! Fast shipping too. Overall, a great experienced on this project. Very satisfied!!
BA3 is one of the best sounding preamplifier that I ever built.
I got ten pairs of J77 & K214 MosFets, so I keep 3 BA3 PCBs for spare.
