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.
diyaudiostore is totally among the best!
Good quality but the solder pad for power transistors could have made bigger.
For college Electronics final project
Combined with my Duel mono ACAs In my hand built backloaded pause text BK 20 speakers I definitely will pass electronics analog class. Instructor is an audiophile amplifier nerd 👍. Next semester‘s class tackle the Alpha J Mono Blocks.
