Detector bias cable to nnaida3 & 5 adaptor PCBs *but* LK1 fitted to nnaida9 *not* nnaida5.
This has been set this way since start of current series of tests Wed 27 April. Connecting
via a different adaptor PCB to that connected to the CAEN N1419 bias supply causes significant
noise issues presumably due to high resistance path via 2x adaptor PCB to DSSSD cables
and the DSSSD bias bus line on the DSSSD.
