Ah, those figures seem more reasonable - 30pF seemed a bit low. Well, I'm not sure what you should be on the lookout for - as you say, it's a completely different animal to having a 3uF in line with the S2. What I would suggest, and this isn't ...

In the past you've referred to current loading in the context of cable length. I recently experienced this when I experimented with moving my amps. I needed to increase the IC length from 1 meter to 3 meters. The only IC I had at that length was an o...

I run the driver tube at 170V @20mA. I don't think you need to run this tube at high current. It is very linear with wide signal swings at this bias. I can get roughly 70Vrms out of it. Output stage clips first, driver continu...

The MiniMe, as much as the rest of my playback have lost the “novelty”. I do not do or planning to do anything with audio. I have found the way to calm down my Focal tweeters and it… will die this way. For what MiniMe meant to be it does very goo...

[quote user="cv"] Don't be pissed about me keeping you in the dark regarding the ribbons; your comments elsewhere on the Nolas and ribbons in general had me loathe to make any recommendations. I think we may have very different tastes in terms of tre...

That's one big tweeter, Romy, and, typically, it was made that big only because they intended for it to go low. I keep wondering about the effects of the extra mass, if nothing else, but also about dispersion and window blind effects ...

[quote user="Romy the Cat"] Considering the problem you described, it was pretty much, where I expected it to be. However your explanations are kind of sound strange to me. If your tweeter were out of phase with the rest of the drivers then it would ...

The EV 350 cones are still available form many sources, they are $25 per cone. There are some other phenolic domes for 1” driver, or smaller. I do not know anyone who does 3”-4” phenolic domes that would make them suitable for MF drivers.
As far as ...

Just how important are subharmonics and undertones in audio, and how they affect tone? I played around for a while with the Townshend supertweeters, this is a ribbon tweeter that you can barely listen to: you plug it in and put it next to your...

I still would hesitant to short the scene and anode and it would require a very sever control of the tubes. The problem is that it would be necessary to do not only then they new (it not too difficult to put then before a fast scope and to see if the...

Alas, not much time to deliver the promised treatise...So, tantalisingly, I will suggest this; for the range 1k up, you would have no problem getting a small mumetal OPT made suitable for the 6C33/S2 combination. Actually, I have something simil...

Cody, this is a kinder, gentler GSC than in earlier times, but FYI your ingenuous intro is just the sort that used to draw heavy fire here. The only reason I have responded at all is because you got me thinking about what I do and don't like about el...

I helped Romy shuffle around some hardware and connect some cables yesterday. That damned table weighs about 100.000 pounds. This was one of those once-in-a-lifetime opportunities to see live, in-person how Romy thinks about audio and incorporates th...

well, i believe that the popularity of the better fostex tweeters comes from their typical, off-shelf sound which is soft and easy on ear in comparison with super-resolunt Ti or Be diaphragm equipped competition. they very much suit any sharpness com...

[quote user="jeff1225"] …"whatever that means" is that most rooms at a trade show are not good. You know this Rommy, I've seen you write it in past posts. [/quote] Shure, Jeff, I know what most rooms, if not all, at a trade show are not suppose to be...

[quote user="el`Ol"]Here is the link:http://www.rank-concept.deI have no experience with the Lamm ML-series, I just listened to an M-series hybrid amp combined with the Watt/Puppy 8. This performance was a single fake (though a pleasant one). I can´t...

Johan, I understand what you are saying. This is kind of James’ barn thread and if you do not mind can you share with him one thing, I think that many others, including me, would be interested to learn the answer to this question: What did you gain g...

Hello Romy,
I just saw the photos - looks like fantastic work by Aleks.
As for the gift - well, if the project is a success and me and other S2 users can buy tweeters with that spec and sound , and without the risk and R&D costs - surely that's a g...

Hi Romy,I think you may be struggling to get 10-12db of gain out of a spud amp (the term is a play on "one tuber").... May just about get it with 6C45.... remember you will be stepping down something like 12 to 18:1 on the OPT.best case: 10db require...
