No i haven't since I lost the coupler signal. But i have a parts board thats helping me follow traces and find designators. I will try swapping the op amp. My new parts wont be here for a week or so yet.
The op-amp, in general, appears to be OK (although it could be leaking internally).
The RCA shield isn't a good reference this far into this amp (and many other amps). All of the -0.546 values are likely 0.00v (at ground).
