Has anyone tried some NOS 805s in comparison to the current production variants? I have RCA 805s and Amperex 805s...


Unless I missed it, and I'm pretty sure I didn't, no one has NOS 805s in their STR. I'm looking forward to your review. I have considered NOS 211s, but so far have resisted the temptation.

Does using an STR impact the Decware warranty?

Hey, duaneh, that's a good question. I would guess that, yes, it does. Perhaps someone has had a chance to run it by Steve to get his position. I have to call Decware this week, so if no one knows one way or the other, I'll ask Sarah. If she does not know, I'll see if I can ask Steve.

FWIW the wording of the warranty is:

Quote:
[The warranty] covers any defects materials or workmanship and
includes both parts and labor. Shipping is not covered. Damage to the amplifier from
improper use, incorrect fuse size, shorted tubes or the wrong tubes will not be
covered.


So the way I read it is if your amp fails because something goes wrong with your STR you aren't covered, just as you wouldn't be covered if something goes wrong with your conventional rectifier, or other tubes. If you are using the STR and the amp fails for an unrelated reason then you are covered. But, as a practical matter it is hard for me to imagine a rectifier related failure, STR or conventional, that does anything more than blow a fuse, or two. But JMO/FWIW and all that. I’m not using mine in a Decware amp.

Tony- Thanks for checking with Decware for us on warranty coverage.

CAJames- “Not using it in a Decware amp” …🤔Good idea.

You know that’s a small price one might have to pay for the results an STR provides.  🤩

So far so good🤞

The Elrogs have landed!



The tubes are several years old, so well broken in but have been in the box for months. They've been playing for about 30 minutes and are clearly better than the Chinese tubes: bigger, more detailed sound and even more dynamics and rock solid bass. At some point I may adjust the other tubes, but for sure the best sound yet. I would probably be less happy if I payed full retail for new tubes, but these were reasonable compared to e.g. TOTL Chinese 10V triodes.

I quickly decided to swap out the warmer, more forgiving input tubes that worked best with the Chinese 10V triodes and put in the more resolving, dynamic input tubes that tend to be my favorite when everything else is right. (This is in my Woo Audio WA22, to which the STR is attached).

And it was another OHMYGAWD moment.

I'm struggling to find the words to describe the sound now, the best I can to is "refined and energized." It is like all the audiophile traits: the detail, the soundstage, the dynamics that were all there before just fit together so much better now, and it a way that makes the sound much more than the sum of the audiophile parts. Everything just seems so (much more) real. For whatever reason I listened to a bunch of vocal music, from Astrud Gilberto and Leontyne Price to Muddy Waters and Mark Lanegan and everything in between, it is just spooky how alive each singer sounds. And how real the backing musicians sound. And how big the space in which they are playing sounds.

I'm reflecting on my experience with 300B tubes, inexpensive Chinese that sounded really good and expensive Takatsuki that sounded better, in ways that were small but important. At that time I felt like the Taks were worth the money, for the same reason that my UFO25s are worth the premium over my UFOs. The budget 300Bs and the plain UFOs were great, but once I heard what was possible with the upgrades I wouldn't want to be without it, even though in absolute terms the differences were pretty modest. I feel like the Elrog 845s are a bigger upgrade than either the Taks or the UFO25s, and now that I know what is possible I wouldn't want to be without them either. Even if it meant buying a new pair.

Not sure where you got that, but more like $1600. Which is still a lot, but same ballpark as TOTL 300B tubes.

CAjames - just a quick search that came up with this seller.  Sounds like a “Top Fishing” seller…above my tube PP.

Yeah, and/or an old webpage. Now you buy them directly from Elrog.
