Marshall JTM 60 - Blows fuse
My son has a JTM60. He retubed it a month ago. A few days later it didn't work. The repair person said he replaced a transformer or something. A few days later it wouldn't go on again. The repair person said he had to replace a fuse and my son should be sure to warm the amp up before using it. Well, it has failed again. I found a fuse blown inside that appears to be a 6.3A. There is no writing on the board to say what it is supposed to be. I plan to replace it with the same rating. Is he blowing these because of settings? I am wondering if they blown on power off rather than power on? Any ideas?
