dustie | Marshall RI blowin fuses I have a Marshall 50W MKII RI that I have put a Hoffman Plexi board kit in running EL34's and everything ran fine.I then chnaged the amp over to EH6550's and rebiased.The amp ran and sounded great for several days but is now blowing the 3.125A main fuse.It blows the fuse on start up even with the tubes pulled.Sounds like a bad PT?What else could it be? TIA |
