I tried an inline inverter. Tough to use as the input to the driver cannot go negative and the lock box doesn't really put out a negative DC. As a result, when you flip (the positive) signal you get something negative or close, not much room to operate. Also, one of the inverters seems to rail which is problematic.
 
Also, interestingly, looking at the previous lockbox, there doesn't seem to be any discernible square-wave bleed-through to the error signal monitor. ISeems thinkto thatbe mayi behad relatedthe input set up wrong when i converted the differential amp to ourone issuesinput. Instead of grounding the other opamp input, i was actually looking at the differential of the power supply rails, that where the square-wave noise bleed through was coming from. That's taken care of, but the slow feedback still doesn't work. hmm. gains? try inversion again?
 
 
-bad component? but the ramp works fine, most all of that is working
-some strange coupling? it is weird we can see discontinuities on the error signal that correspond to the square pulse, do we see those in the other lock box?
