So I'm working on fixing this tube amp. It's got something wrong on the B+ supply. Probably the transformer, but anywho...
The B+ is fused. Now, since B+ are typically 300VDC+, what kind of fuse should go in there? The existing fuse didn't have any specs on it besides amperage, and it is my understanding that voltage ratings are a "go under, not over" kind of thing. I can't seem to find any 1A fuses at a voltage of greater than 250. They are also rated for AC. I need a DC fuse. Can someone please clarify this for me and maybe point me to where I can get a suitable fuse?
