Log Number: 4516101Logbook(s): Body: 

Replaced arc detector PMT in 1L21-5 and 2L07-4 and manually tested fine. 2L07-4 was logged as GSET 0 due to arcing in which case it will have to be derated. Cavity also has high KMAI/KMAS and SOS'ing since August last year which will require derating to correct.
