Hegel fuse holder

Don't know what your Hegel uses, but there's only so many different designs. The trickiest are the tiny little ones with only a small slot you have to use a very small screwdriver to lever them open. The only image I could find on their website it looks like that's the one they use, integral with the IEC power socket. Try a very small, thin screwdriver, or maybe a pick.

That’s where I’m at - small flathead screwdriver, maybe a penny. I want to try out the SR orange fuse, just worried I’ll crack the plastic open and then really be screwed.

If it is the one with the slide out drawer, just use a proper sized screwdriver and gently twist it sideways a bit, to loosen it. Then try to leverage it all the way using equal and gentle force along the whole of the edge of the screwdriver. 

That's how I do it and it still leaves gouges and marks.

All the best,
Nonoise

Got it! These things are gonna come out with tweezers...they sure don’t make this easy 

Orange will blow your mind. Not because the improvement will be so staggeringly huge. But because the fuse is so small its hard to believe it could make ANY difference at all! Witness all those around here who still don't believe it! Even after a bazillion people try and hear and say yeah it is for real. 

If you can find a screwdriver with a blade as wide as the slot but still thin enough to fit in there and twist like nonoise said that is ideal. Otherwise don't worry, its not like this is something you do a lot, its in back and hidden by the power cord anyway.  

I like to Scotch tape the factory fuse nearby or preferably inside so its there as a spare and so when the amp gets sold the factory fuse goes and the SR stays!
