Hello - one of my fuses blew and I replaced it with a MDL 2A -250v Fuse. Once I turned the amp on and played for a few minutes, I noticed that the volume was very low. The amp felt extremely hot and one of the tubes blew. The back of the amp by the fuse box says it can take the following, T2A - 230v T4A - 120v I live in the U.S. Can someone recommend which fuses would be OK for my amp? Having a really tough time finding an exact match. Thanks!
