for lack of other ideas i've been putting the lockbox circuit in multisim to verify that the gain and phase-margin are sufficient for our application. No startling revelations as I looked at it when building the first box. A few ideas:
-50ohm coupling resistor?
-insufficient gain? Check error signal magnitude on the SHG lock and see if they're vastly different..
-something just not connected? since the ramp and the FFB work, there's a pretty narrow amount of stuff that may be messed up, look in the circuit?

Another day, another crack at circuit debugging..
