I finished making the modifications to box #2215 (aka "box 2", "the CW box", "the AOM path box", "Killer" etc etc) so that it is identical to #1437 ("box 1"), which Rana modified a few months ago. Attached is the transfer function, which you can compare with that of the other.

I plan to update the schematics and put them---along with these transfer functions and pictures of the boxes---on the Gyro wiki.
