    open light leak and check single ph.e. signal from PMT #9, it is ~ 100 mV at
    HV = +2400 V, which was used in the run, so signal has good value
    took base from PMT #1 and put on PMT #9, now HV come from module 2.8,
    HV = -2800 V
    install positive base #103 on PMT # 1, now it get HV from module 15.8, HV = +2600
    close light leak. Channel 2.0 will be OFF from now.
