hi guys, greetings from china 
I'm new to acoustics and diy. About a week ago I watched a video using two op-amp AD1642 to drive a capsule (dual op-amp alice). Thats so cool, immediately I draw a schematic and learn more about pre-amp circuit.
I already draw a PCB with a JFET and 2 BJT. I find so many useful resources here on diy a capsule so i decided to make a capsule myself.
First time to deal with audio, wish i can enjoy here and learn a lot
