keyword=Right Arm VDCs - one cable unplugged - one cable flipped
Looking at the Right Arm VDCs. I found the cable 'LOWER U6' flipped at
the TDC. The 'hot' wire was the grounded pair connected to the TDC input.
The cable is now plugged in correctly. I found the cable 'LOWER U23'
unplugged at the amplifier end. I plugged it into the LeCroy 2735
amplifier card.
On the top VDC I removed the amplifier at V17 and inserted the amplifier
that had been at V23. We shall see if that does anything. I left the
amplifier, which was removed from V17, by the V23 end of the VDC.
