fuse holders stainless steel fasteners esd heel strap FUSE HOLDERS Irwin Industrial is a manufacturing company engaged in the design and sale of Terminal Blocks and Fuse Holders, which provide interconnection and circuit protection of electrical systems. Fuse holders are devices for containing, protecting and mounting fuses. The fuse holders are attached to a steel bar which, in turn, is fixed to metal supports attached to the side panels of the box. The melting of the samples is observed with a magnifying glass attached to the plastic cover of the box. Terminal blocks and fuse holders are used in electrical and electronic equipment. We offer three types of fuse holders; printed circuit board spring clips for mounting fuses right onto the pcb; a fuse block with black plastic molded base which can be mounted on a chassis or circuit board; and a black plastic, spring-loaded, panel-mount fuse holder for mounting onto front or back chassis panels. The speaker cable is spliced to a pair of automotive-style fuse holders. I used lots of heat shrinking tubing to keep the splice protected, as well as to bind the two fuse holders together. These are in the large fuse holders located on the back or top deck of the amplifier. Most likely there is a blown "plate" fuse in the channel in question.
