We mount back all preamplifiers Initially we used all the PA coming from US, the repaired and the new ones. There was an issue with the new ones (strong noise and cross talk) until we realized that the new ones were of differential type instead of unipolar. We decided to mount all unipolar so we use the repaired ones plus the ones which were left here and had some minor problems with discharges. We decided to change slightly the gain of the pulser signals because for PA6 to PA10 the amplitude after the preamp was 2.2-2.4V so it was saturating the ADC. So we decreased Pulser 1 (RIKEN, ORNL1, ORNL2, CLOVER) from 690mV to 540mV (NEG) on the scope (50ohm) and increased Pulser 2 (UPC) from 90mV to 100mV
