Blown output fuse on vintage threshold amp
I have been looking for a replacement fuse, but am a little overwhelmed.
The requirement is for a 4amp, 3AG, fast blow (~30mm). I’ve heard that ceramics might “sound” better and I am open to trying, but I’m finding it difficult to select one (or a few) that will work.
Will any fuse do that meet these specs? Any recommendations or interesting alternatives?
