    "Internal Fast Blow Superfuse"
    I have a number of Russ' standard Super Fuses in use and can confirm these smaller, internal fuses work just as well. Is £25 a lot for a fuse? Well yes it is. Is it a lot for the extra clarity and reduced distortion that results? I think not! In fact I think it's a something of a bargain so, treat yourself today.
