Moog Ladder Filter – operating at 12V

I was frequently questioned if my design of the Moog Ladder runs at 12V. The answer is yes. You can run it at 12V out of the box. However the performance at 12V can be optimized by changing a few resistors.

– R47 and R13 from 13k to 11k (Diode bias current for LM13700).

– R56 and R2 from 13k to 10k (I_abc for LM13700).
