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.
A very good quality board.
diyaudiostore is totally among the best!
Good quality but the solder pad for power transistors could have made bigger.
