If your AC30CC2 is blowing the fuse under the IEC connector, you probably need to replace your rectifier tube or some other repair, then replace this fuse.

Arrived quick. Doesnt match the photo perfectly but it they work just fine. The first fuse did blow right away and the 2nd one I put in didn't, so not sure if it was an issue with the fuse or the product I was putting them in.

This size of fuse is nearly impossible to find in a 250V, 4A configuration. These fit the bill great. We use them in a Land Mobile Radio environment, where they protect the 110V AC input to a 12V DC converter in a desktop base radio. The power supplies themselves are crap and blow the fuses on the AC side a lot. These fuses have been great quality replacements.
