Subject: MC1 Coil Driver pulled out 

I have pulled out MC1 coil driver board from its Eurocrate, so IMC is unavailable until further notice. Plans:

  1. Thick film --> Thin Film
  2. AD797 --> Op27
  3. Remove Pots in analog actuation path.
  4. Measure noise
  5. Route HPF signal (UL DAQ Mon) to front panel. I think we should use the SMA connectors. That way, we have DC and AC voltage monitors available for debugging.

If there are no objections, I will execute Step #5 in the next couple of hours. I'm going to start with Steps 1-4.
