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!

gotta say miller is spot on and knows his stuff. I was one of those non-believers and gave it a shot. Now my fuses, interconnects, speaker cables, PCs and new Powercell UEF SE in my system are just phenomenal. Oh yeah HFTs too.
‘I’ve been a critical listener for almost 40 years and my system has never sounded as good as it does now. SR is not, not snake oil.

I imagine they’ve got good stuff. Started with Bybee QSE, then an iQSE, then quantum Clarifiers in my speakers. Anyway, those tweaks are so good, it’s hard to go back. 

Tweaks rule. My system is so tweaked out it would take pages just to list it all and the crazy part is it works so good I only want more. To get some idea, take what you've done, multiply by a hundred. https://youtu.be/zZcZ6eJoxeE?t=9   This will totally trigger the Film Actors Guilds, if you know what I mean. But whatever. Stuff totally works. 

ECT, PHT, ditto. PPS, TDF, fO.q, Townshend, BDR, it really adds up. Its been a while now since the last round of tweaks adding fO.q tape and Active Shielding to the turntable. That left me slack-jawed for a good long time. Only now beginning to get used to that quantum leap. Just in time for more Townshend Pods for the Herron..... did I mention, tweaks rule? Buwahahaha!

Ok, got the SR Orange in. What's the deal with the grey charcoal looking circle in the middle that they tell you not to remove?

I think I have it in the right way with SR facing left to right when inserted.

I also have a Hegel, and would like to see a video, how to open this little door, without breakin the plastic cap, and al;so to see the correct direction of the "orange fuse" how to install into the fuse holder ?

My Aurender has the same fuse holder thingie. I had a difficult time opening it but the Orange fuse made a significant improvement although it takes over 100 hours to break-in. 
I've a number of Synergistic Research products including cables and resonators. All worthwhile even for a guy with a limited budget like me.
