Subject: Gain blocks installed 

Jordan will write up the detailed elog but in summary,

  1. Former +24V Sorensen in the AUX OMC power rack (south of 1X2) has been reconfigured to +12V DC.
  2. The voltage was routed to a bank of fusable terminal blocks on the NW corner of 1X1.
  3. An unused cable running to the PSL table was hijacked for this purpose.
  4. The ZHL-1010+ were installed on the upper shelf of the PSL table, the two gain blocks draw a total of ~600mA of current when powered.

I will install these at the next opportunity, so that we can get rid of the many attenuators in this path (the main difficulty will be sourcing the required +12V DC for operation, we only have +15V available near the PSL table).
