 q31 creates the current that controls the amplitude of the vca\\
 q1 through q4 are merely current mirrors to reflect this current appropriately to the 6110 since it is different than the 662

+[[http://www.ladyada.net/forums/viewtopic.php?t=5673|The]] output of the BA6110 is a few dB hotter than the BA662, I measured as much as 5dB.
+If using the BA6110 changing R155 to 100k will give the same performance as a tb-303.
+There will still be some distortion with higher settings of volume and accent - the tb-303 does it too.
+Or you can simply turn down the volume control down until it doesn't clip (the 'mixer' stage is after the volume control).
