Max amplitude histograms for cosmics at 2100V with 50/50 Ar/CO2
Left: new preamp and new HVB, ADC half-range; right: old preamp and HVB, ADC full-range
Purple: untracked, blue: tracked (less of this with old preamp because of 2 dead central channels)

New preamp and HVB - max amplitude histo for cosmics at 2100V
Old preamp and HVB - max amplitude histo for cosmics at 2100V
