DIY microphone buffer boards

I ordered these PCBs for DIY microphone projects. I did not invent the design, thanks to sound sleuth and JLI electronics. I tested the boards yesterday and they are marvelous buffer boards and they have more amplification than I thought and help to push down the noisefloor significantly. PCBway produced these boards perfectly, fast and transparent.
