Synergistic Red Fuse ...

+1 on Andy of Vintage Tube Services. He's a wealth of tube and vintage gear knowledge and a great guy to deal with. My only tube source.

While I just started using tubes last year I've done a decent amount of tube rolling and enjoy the different sound qualiies different tubes bring to the table, especially NOS tubes. A matched quad of 60's NOS RCA 6L6GC's black plates have transformed my amp.....purely magical. 

Good point geoffkait. I wonder what people will think if I get small tube dampers to to fit over my fuses? It actually might not be a bad idea!

I hate to judge before all the facts are in but (and I’m only going by what others have said on this dodgy subject, not to mention own extensive experience and the testimony of others) can I be so bold as to suggest it’s possible you’re following the wrong sheep?

No problem, Jetter.  To be sure my thoughts about fuses are clear, here is a summary of the major points I have made in this and other fuse-related threads:

1)I don't doubt that fuses can make a difference in many applications, even though ...

2)... Measured data that has been presented in support of the existence of those differences is not supportive of their existence, for reasons I have explained.

3)I have expressed bafflement at how any particular fuse, such as the SR Black, can provide the benefits it has been reported to provide with the high degree of consistency that has been reported, among components that are completely different in design, that perform completely different functions, that are used in very different systems, that are powered by AC having very different voltage and noise characteristics, and in DC as well as AC applications.

4)I have contended that it is impossible for a fuse to have inherent directional characteristics.  See my post dated 12-31-2016.  And I have said that even if a fuse did have inherent directional characteristics, the vastly longer associated wiring would as well, and the directional effects of that wiring would swamp those of the fuse.

5)I have pointed out in this and other threads that in audio it is often extremely easy to attribute a perceived sonic effect to the wrong variable.  And that the methodology with which an evaluation is performed needs to be especially thorough in the case of tweaks that are technically unexplainable and/or seemingly implausible, to rule out the possibility that unrecognized extraneous variables are responsible.

Also, regarding the question of why "non-believers" keep coming back to this thread, as would be the case in most threads discussion of that question is, IMO, neither constructive nor germane to the topic of the thread.

Hi Al,

A fine and balanced summary as always.

I will be surprised if anything more than what you stated is ever discerned about this topic.

Best to you Al,
Dave
