You don't happen to have a curve plotted of that?
Is it possible to take that into account and trim the input for minimum 
worst case bleedthrough?
How does the use of linearizing diodes affect this? Or should I just 
forget about them for the voice final VCAs?
How bad is the CV bleedthrough for untrimmed 13700 circuit?
