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.
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.
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!).
