Hello, I'm a Nagra Classic user and I have a question.

What is the direction of current in a fuse circuit diagram? Is it from bottom to top or from top to bottom? I'm replacing the fuse in my audio equipment, but fuses are directional, and I don't know the correct direction.

Seriously…
Why?
 
Unfortunately I think you have to try both ways after the fuse is broken in. It's something I should try on all my gear, I use the hifi tuning fuses to. So either I got lucky or It has more to offer. I run my hi fi tuning fuses with lil arrow pointing towards the socket as you plug it in....

PS I haven't tried the new diamond supremes...I have all silver gold supreme in everything...

For real?

Doesn’t the power supply ameliorate everything?
 
The power supply very well could. Lots report fuses are directional. I just use one direction and it always was such an improvement I never fooled around with flipping it...Our Nagra dealers or Nagra customer service may know the true answer...I'll ask mine
 
The fuse orientation for the Nagra Classic series is confirmed as shown in the image for reference. After experimenting with several other fuses, I used the Synergistic Research Master preamp and the HiFi Tuning Supreme 3 Diamond silver power amp. Personally, I think it sounds fantastic and is also the closest to the original factory bass tone (I feel there's almost no change). It sounds great, and I'm sharing this for your reference.

Thanks. I assumed it was that way...just got lucky. As far as the fuse orientation. How did you determine that?
