Eared replacement fuse holder clip.
“Eared” means the fuse will not slid out, and fit tightly; these have to be soldered in with the ear to the outside.
Buss, rated for 500 volt, 30 amps.
Always a good idea to change these if your rebuilding a older pin.
Do a “fuse clip” stress test, remove the fuse, then squeeze the clip together, chances are it breaks.(see photo gallery)
If that happens, it needed to be changed.
These fit all, but are ideal for replacements on the older Bally / Stern power rectifier boards.
