    keyword=A1 pmt replaced

    Armando and I went in and replaced a PMT on A1 corresponding to channel 10 of the histograms. [Sunday owl had shown that the tube/base combo was dead but at the time we did not a pmt ready to replace it with.]

    The signal looks good from this tube, but it does need to be hardware and software gain matched. Armando took the old tube from the hall and will check whether the culprit is the tube or base.
