     Ciao guys,

     looking at LAMOSSKA events on SM5, I found another bad PMT: 5B07-0.
     Using the scope, you can see that it is very bright and it seems
     to have 2 gains, one at 4mV and the second at ~5-6 V.
     This counter has ~ 3.5 mHz of trigger rate on TOHM.
     I think we have to open this tank too...

     A dopo,

                             Nicola
