Burning Amplifier Local Feedback Gain Stage
- 1 x Burning Amplifier Local Feedback Gain Stage PCB - Dimensions 140mm x 70mm
Burning Amplifier Gain Stage Board (BAGS) which handles voltage gain for two channels when you populate it with your components. This board is required for both the single-ended BA-1 amp and the complementary BA-2 amp.
BAGS is the Burning Amplifier Gain Stage board. Being the Front-End, this is where all the signal voltage gain of a Burning Amp comes from. It's main purpose is to provide adequate gain to drive the succeeding output stage of a Burning Amp assembly.
For use as a Burning Amp, it requires bias boards and output stage. However it can also be used standalone as a pre-amplifier.

ADDITIONAL INFORMATION
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.
