Most of my customer have used the grounding style indicated in the layout successfully. All efforts have been put in the PCB to minimise hums, and there're are two large copper pours, one for the preamp GND and one for the power GND. Try that out and let us know how it goes ;)
Hi Robert,
Most of my customer have used the grounding style indicated in the layout successfully. All efforts have been put in the PCB to minimise hums, and there're are two large copper pours, one for the preamp GND and one for the power GND. Try that out and let us know how it goes ;)
How's the build proceeding?
Best,
