NEW PROTOTYPE FUSES COMING >>>

I’ve been asked to evaluate/beta test some new fuses that will be coming out soon. I should have them as soon as this coming Saturday.

At this point:

1. I cannot reveal the name of the manufacturer of the fuses.
2. I do not know what the retail price will be.
3. I do not know what the name of the fuse will be.

For comparison purposes, I have a full complement of SR Orange fuses that can be used throughout the system. I have one QSA Yellow fuse now being used in my ARC-PH8 phono stage, with another one to arrive soon to be used in my ARC REF-75se.

I’ll be comparing the SR Orange fuses, and the QSA fuses, with the new prototype fuses. I’ll also be using the ears of three of my well-seasoned audiophile friends, as well as my own to make the evaluations. These guys are all truth-tellers that I have full confidence in.

According to the manufacturer, these new fuses are real game-changers, so stay tuned.

Top-Spin Quark can explain it all….

I suspect, you went fuseless on the Maggies ?

That is a mistaken characterization, my RM-9 serial # 536 came from his bench w Wondercaps…. arguably the first “ boutique “ cap.

of course some skin in the game warranty claims might had something to do with his disdain…perhaps you can clarify RM’s question about the suitability ( compliance to a specification )  of that particular fuse for use in a high voltage tube circuit…. ?

What is the warranty on gear you modify ?

Agree on the warranty claims and how that would cause one they have a certain view on boutique fuses. I am actually making the same point.

I have no idea what you are referring to in terms of the actual fuse value in the amplifier in question. Don’t know if it was a lower rated fuse, fuse rated in spec, fuse rated over spec?

In the end,  it really doesn’t matter because the fuse did not act as the designer wanted and caused some major issues. I would stay away from those particular fuses from that manufacturer in that amp 😁

JW Blue, Jim? Now yer talkin’! I bypassed the fuse (in fact the entire fuse block, as well as the horrid speaker connectors, installing Cardas binding posts in their place) in my Magneplanar Tympani T-IVa.

Roger’s views on audiophile parts is often over-simplified. He DID consider electrolytic caps unsuitable for some applications, fine for others. It’s all in his AudioCircle writings. And he was making speaker cables at the end, and not just to make money.

It was the use use of fuses that were not of "high breaking capacity" design that he warned against in his amps, and in fact as part of any amp to which such a fuse was connected to output tubes. He received back at his shop an RM-9 that was destroyed by a full compliment of Hi-Fi Tuning fuses which did not preform their primary task: protecting the circuitry they were connected to. 12 non-performing fuses which cost as much as the amp itself? Ridiculous!
