Congrats! You will be in love with it by tomorrow.

I got the Super Duper Sluggo (tellurium copper with rhodium plating, a thing of beauty) in and I think I may have put it in in the wrong direction but it's a very nice sounding piece of metal!

I only have 16 cumulative hours and counting.......
Decay is blowing my mind .....going deeper into the stage too.

Thanks, Groovy Sauce, HK for pointing me to this thread immediately.

Stone, it will get better day by day for a while.

I'm enjoying the sound of the Super Duper Sluggo. There is only one drawback: it is milled to look like a fuse, and as such it is a bit smaller. That is a good thing I think sonically--the lesser mass makes it "push" the current just a tiny bit less, but it also means that when removing the fuse in the Decware fuse holder it generally pops out and rolls around. . . and it's easy to confuse what direction it was in previously. I'm still not sure that I have changed direction in the three times I've had it in and out! I'm going to put a Sharpie dot on one end next time.

Took me four tries but I have the Super Duper Sluggo in the SEWE300B in the right direction and it has been seasoning in steadily. . .

Wow. With the hollow silver slugs in the P15 and the DSD DAC Mk II I am getting just the right tonal balance, the "just right" I've been searching for for some time. Mark called this one right, a great recommendation.

Now: a reminder to myself: don't mess this up! Stop futzing!

I don't think mine do--I'll look closely soon.

I've only changed a fuse when it blew, that has happened maybe twice in my entire life. So this is all new to me.

We have a Sarah 300b and love it, we are using the full Wathen CryoTone tube set and at low volume you can hear a slight hum (even when dialing the hum down with the hum control). We swapped out tubes and still had the slight hum.

Does the Swiss Digital FUSE BOX help, reduce or eliminate the hum? I'm hoping to hear from someone with actual experience using the Swiss Digital FUSE BOX with a Sarah 300b.

Thank You,

Lon,

Thank you for the quick response!

We have all the top of the line Decware plugs, xlr and rca cables along with the ZSTYX speaker cables.

We have a zbit and zrock II we'll play with them a bit, the hum is only noticeable at low (background type) volume.

I'm new to tubes just a few years, what tube(s) number would the 75C1's replace?

Thank You,
Steve08226

Lon,

Thanks a lot!

Steve

Steve,

I have used almost a full compliment of Cryotone tubes (sans the the 300B) and have not experienced audible hum on my Sarah.  Whatever noise I did experience was because of a noisy WE 300B and the second I replaced it with the stock 300B that came with Sarah, the speakers were dead silent.

And outside of Lon’s experience with initial hum with the Cryotone 300Bs, I’ve read other accounts where the same tubes had no hum whatsoever from the get go.  I should also have some firsthand experience with it in 2 weeks after I receive my tubes from Don.

Hope you figure it out.

Awesome! So happy to read this result.

Great news Will! I have two of these hollow silver in use, and one Super Duper Sluggo in the third SDFB and that combo is very nice, especially with the Black Treasure 300B-Z tubes you sent.

LIkewise I hope the Psvane I sent work out, I think they just might be really good as driver tubes.

I've been missing the Aqua 274B II but the original Aqua with these 300B-Z are gelling really well and the 300B-Z are settling in nicely, opening up a bit without losing the characteristics I really enjoy.

Hey Tony... both places I tried for hollow fuse replacements advertised with the same pictures, and the same choices... so guessing they are the same. Both were AliExpress sellers. The first, cheaper offer fell through for some reason, finding out later they had started a refund to my paypal account. So I ordered from the 2nd, higher priced seller (for these anyway).... Hope this helps.

Will

Lon,

I look forward to hearing those Psvanes in my amp's driver position... The original ones with this amp were Psvane globes, and have nice qualities here. It gets so specific with such tuned systems, criteria becoming narrower, but from your description off-line they sound like they will be good for me! Excited to hear them.


Hearafter,

I have not tried my hollow Platinum/Rhodium plate silver fuse replacement yet, but there are several posts in the thread about the Verafi "Super Duper Sluggo" which I think might be translated as tellurium copper with rhodium plating??? Lon has recently talked about it, and others earlier as I recall. I don't remember anyone trying the hollow one like I have, but I may have missed it. Might search the thread for super duper sluggo or Rhodium.

Staying with the HP Copper for now. The kaleidoscope continues to turn in focus .....providing all of the kaleidoscope there created by the System. It continues..........

Considering one from wall to PS Audio P3. However, I'm so pleased with the PK10 Palladian from wall to P3.....providing input. In which I prefer running my ZMA/SDFB and ZDSD/Shunyata from the HCurrent outlet.

Lon, you're pleased running SDFB to P15.

Good Afternoon

Just to let everyone know - the Graphene Sluggos have just arrived in Texas

I think they are pretty dang good - but that's me.

One day soon I will be home and listening again

Many thanks - Mark

Super Piggies due to ship Friday after a long delay.

Vendor has them ready to go

Longer Length and better in every way

Pictures to follow

Thanks - Mark

I have to stop spending money on audio. The Graphene Sluggos are intriguing me, I'd love to hear more about their characteristics. But I'm not ready to purchase in the near future. Love the Super Duper Sluggo's influence on my system.

I decided to try the Cryotone 5U4G . . . Kam loves it, and it doesn't seem to be a JJ product. . . the "softness" that the description on the site mentions is a draw. It occurred to me that the reason the Aqua II failed on me was that I kept turning the amp on and off while trying different Sluggos and different directions of Sluggos. I swapped over to the original Aqua which worked really well with the Black Treasure 300B-Z (I can recommend these tubes to anyone who is seeking a more dark and romantic sound) and today I put my only remaining Aqua II in from my CSP3--the little boost in sound quality is nice . . . I hope that it will last as I don't plan any frequent on and off cycles.

Super Piggies are on the way (at last)...

I only have 20 to ship now - have ordered 50 more

We have to get some pictures up etc. on the site. Damien is busy with SnubWay arrival and shipping - that's primary

These will be $150 dollars and they are much longer than piggy (1 meter). Super Piggy is Super Cool Sounds great and works wonderfully well.

We also now have Schuko Piggies in stock - these will be added also

Many thanks

Mark

Of course, I needed to ABA it even at the 35 hour mark. Happy camper. I DeoxIT 'd it again too. Always, takes a bit (hours)  for that to settle in ......bliss right now.

Glad you arrived back in time to experience this great new power assistance.

A new review from Positive Feedback:

Yes. Congrats Mark.

I am still sitting with my HP Copper and enjoying. I don't want to reverse it or order other Sluggo's yet.

Look what arrived today in the mail... THREE LITTLE (SUPER) PIGGIES!

Thought you folks would enjoy this from Tom Gibbs from Positive Feedback - He was using Super Sluggo... but I couldn't leave it alone.

Scab picked - sent him Graphene

His first post about that

Enjoy

WITH PERMISSION

Swiss Digital Fuse Box Follow-up, Part Deux:
Following my review of the Swiss Digital Fuse Box, Mark L. Schifter sent me a pair of Graphene Sluggos, to replace the gold-plated Super Sluggo that was already in place in the PrimaLuna EVO 300 tube integrated; they arrived yesterday. I'll be honest, I didn't really have the time last night: we ended up getting home later than usual, and I was pretty beat after being with the kids all day and then sitting in hot traffic for an hour driving home, so I just vegged when we got here. So I didn't take a listen last night as I had planned. I just now ran upstairs, and I again put on what's become my go-to LP to hear subtle differences in equipment, etc., which is the Impex Records' 1STEP 45 rpm reissue of Patricia Barber's Nightclub, which is a jazz trio and quartet recording from the late 90's that was recorded by Jim Anderson. It's exceptionally well-recorded, and presents the sound of Patricia Barber's voice and the individual instruments very naturally and dynamically. I've had this set for almost 18 months, and have listened to it countless times since then, and know it very well.

Whoah!! With the Graphene Sluggo in place, I immediately noticed a deeper, blacker background and an improved spatial relationship between the players, which were more well defined in the soundstage. Patricia Barber's voice possessed a more impressive level of realism and presence, such that I felt I could reach out and touch her! The Scouts/Caldera loudspeaker combo seemed to play not only with a greater sense of ease, but with more control from the PrimaLuna amp, especially in the bass and mid-bass registers, where this album can give certain loudspeakers some level of difficulty. Side four of the two-LP set is my favorite, and the final track, which is PB's version of the classic "Wild Is The Wind" was much more nuanced and delicate with the Graphene Sluggo in place. The acoustic bass player, Marc Johnson, offers a really intricate plucked and strummed solo at the song's mid section, and I was pretty astonished by the improved level of realism I was now hearing -- I've always felt that I could localize the position of the players in this recording very well, but this took it to another level! I'm listening in the all-analog room in a near-field setup with the Vanguard Scout/Caldera combo, but I could lean into the music and visualize Marc Johnson's fingers on the strings with a degree of tactile realism I'd never have believed possible. The background was blacker and the soundstage was deeper -- even though I've been listening to the Scout/Caldera setup for months now, it was almost as if I were listening on a much more expensive, more resolving system! I'm incredibly impressed, especially after the shock of first hearing the Swiss Digital Fuse Box inline with the PrimaLuna -- I wouldn't have expected such an additional increase in clarity and transparency was possible.
I've had some experience in the past with Graphene-enhanced products, like the ADD-Powr Sorcer equipment, which coats all electrical connections with the compound. Here's a quote from that review that basically describes the possibility of using Graphene in electrical and audio applications:

"All wired connections are coated with [the] exotic compound Graphene which is an allotrope of Carbon in the form of a microscopic hexagonal layer of molecules. It's the strongest compound known to man, with a tensile strength 100-300 times that of steel. At one atom thick, it is also the thinnest and lightest compound known to man; add multiple layers of Graphene and it becomes Graphite. It's also the best electrical conductor known to man."
For sure, the use of Graphene in the latest iteration of Vera-Fi Audio LLC 's new Sluggo for the SDFB is a huge step-up in overall performance. One of the key points I used in my review at Positive Feedback was that the Swiss Digital Fuse Box allowed my PrimaLuna EVO 300 to perform in an a more unrestrained manner; now with the Graphene Sluggo in place, there are NO RESTRAINTS.

I only thought my mind was blown! Follow-up review coming on Positive Feedback soon!
