Synergistic Research Black fuese

asalerno:

This has happened with a Synergistic Research SR-20 fuse in my headphone tube amp (Eddy Current Zana Deux amp. The amplifier manufacturer had me go to the next largest fuse and since then no problems.

The SR Black fuse really does improve the sound.

Thank you for your quick response. I agree that the SR Black fuses do indeed make a significant improvement in overall sound quality. It is also interesting that you mentioned going to the next largest fuse... I suspect that is what I would try next. Best regards, Al

David,
I did go to the next largest fuse and that did solved the problem! So thank you for the suggestion.  Alfred at High End Electronics was great to work with and supplied replacement fuses in exchange for the blown fuses.  He did share with me that the SR Blacks tend to be on the sensitive side.  The sound quality is a big step up from top to bottom.  It is just amazing....
Thanks!
Al

I am glad you are enjoying the sonic improvement with the Synergistic Research Black fuse. Alfred Kainz is a real gentleman.

If you are still using an ordinary wall outlet, I hope you will consider one of the many good Audio quality outlets available. Fuses and outlets are two areas that really respond to upgrades.

I'm thinking about trying these in my monos but reading there were a couple of occasions of them blowing is slightly disconcerting...the manufacturer state to use sand filled T6.3A so would it be a straight swap or a different rating considering the sensitivity of the Black...??
