    I check data from the latest run #7528. It is clear that
    1/2 of LV on T3 crashed again.
    I think, that shifters should put a special attention on T3 and try
    to recycle the LV on T3 each time it tripped.
    
    I would also suggest to go with T3 HV on anodes backs to the default
    value of 1190, now it is 1200,
    and the currents seem to be too high.
    
    Regards
    Pawel.
