The signals observed at that time are no longer present. All I see is a 60 Hz ripple on PP41 and 42 that isn't on other patch-panel connections -- something's plugged in there, but it isn't very useful.
The PMTs are drawing current so it's almost certainly a cabling problem.
We'll have to get this worked out Monday prior to the pulsed beam tests.
