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.
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.
Excellent board. High quality as usual. Would make an excellent preamp as well.
High quality boards and very good sounding pre.
DIY Audio boards are well made and I know I can trust the design. Their packageing and shipping are also top notch. Overall a pleasure to do business with.
Excellent quality PCB any novice could complete.
If there is a wish list, bigger pads please - less likely to pull away if the circuit is modified later.
The only build issue I have is the heatsinks fins are covering the mounting holes I wanted to use (Note to self, next time, fit PCB spacers first!).
Very high quality board. Quick delivery from the US.
