Build Map for Dual99v3000
http://jlmaudio.com/builds/maps/Dual99v3000_map.html

RPad = 110R
RLoad = 24k
CLoad = 100pF
Adding a second 100pF to the IC2 +in to 0v improves the performance of the mic pre even more

Adjust Trimpot for 0v at TP1 measured to 0v with a multimeter. Done

Gain pot 20 to 50dB. Pull the Gain pot switch outwards 20 to 66dB
