Paul, if by error correction you mean frequency correction then I was thinking about +/- the same.i) Active filters; I have zero experience with crossing-over but people who seem to know what theyare talking about all agree that at ULF active is the ...

Yeah, that is low life for sure but that kind of takedown is becoming more common. People are copying the politicos (of all types and persuasions). If they can't give a memorized answer or it jars one of their buzz phrases they feel free to slime yo...

I am not the person to speak about the 6E5P but I have messed with hybrids. If you want LF power, I can say I've heard some pretty simple plate amps that "work" at LF. It would be helpful, and it might even be necessary for you to tell more about you...
|

Well, that's a mighty interesting hybrid! And talk about current! I'm going to look into that further, myself.
BTW, yes, some MC SUTs are "like that'", but - obviously - they are "LV".
Best regards,
Paul S...

My wording was bad. I am building zarathustra but am a long long way from completion. I do not have the capabilities to just whip one up. Yes the 6n1p was from the old days when i thought i had discovered good sound, i'm sure i still don't know(but...

I am with you on this one. I am also very suspicious of gigantic, 4-chassis phono stages if only because I just wonder why the need for all those damn noisy parts, along with concommitment connections?So it really pisses me off to admit that th...

I think I have had enough time with this phono stage now to make a few remarks about it. In keeping with the spirit of this website I am not recommending this component, just reporting on it.
I got my unit off AudioGon after keeping my eyes pe...

So, it has been a while. I have DSET/Macondo in stereo now although there is still some work to do to finish it and tune it to the room. As discussed earlier in this thread I need a preamp with gain and the Placette is just not cutting it for me (n...

Antonio, you might refer to Mike Lavigne from Seattle, I have mentioned him somewhere at my site. I do not know if it is the same guy but it is not the point. The too much worthless leisure time in my hands is not the point as well. The point is that...

Hi Romy,
Could you explain a little more about the amp? If I understand you correctly it is a 1 tube stage with solid state (Mosfet or Bipolar??) output. If it is Mosfet then it is likely to be running without negative feedack, is that r...

Hey Cat,Well..my first question would be regarding the application. The big Melq tube is already doing the bass towers...is it not enough current? And wouldn't a proper class A 100w amp with its low low efficiency require something like 1...

Rather involved discussion about Helmholtz-type speakers. Here's another proponent, Hans Kortenbach:https://www.youtube.com/watch?v=LHBlikzKoRgI have only "heard" the Musical Affairs speakers on YouTube, but I have to say, they are able to do some s...

[quote user="Paul S"]Scott, is it your specific aim to configure an enclosure to "effectively" lower driver Fs? While this, along with an exponential increase in power, is a proven strategy for generating ULF, it seems like this approach creates more...

[quote user="jamesrm618"]The Vincent SP-T100 looks close "The SP-T100 is a hybrid mono block with tubes in the input stage where voltage is amplified. The power output Amplifier circuitry works without feedback." Nominal output power Class-A 8 Ohm: 1...

Do I remember that a big part of Romy's choice for a pre-amp was based on the specific needs of his DSET Milq, with it's inter-stage X/Os? And do I remember the Placette Active Pre-amp has consistent, fu...

[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...

Have put all my DHT's on the curve tracer to see if pairs can be matched for preamp duties. My stash of 10y/VT25/801a/VT62 are generally all very new or NOS specs with mu and plate resistance varying a little, but generally close to nominal specific...

I thought the B1 was Yamaha's V-FET and the B2 was a later "hybrid", but I suppose both are Vintage Sufferer's wet dreams. I have never heard either amp, anyway.
Yamaha B1 and B2 conceptually the same amp. B1 is made only with one polarity V-...

[quote user="N-set"]And paralled drivers? May I ask why you wanted to avoid them but would accept paralled output tubes?[/quote] I would for sure avoid any paralleling, would it be driver or output. Still, driver provides voltage gain and output stag...

I was traveling yesterday and away from the computer until this evening. I'm glad to see my post as the source of controversy and even cause for a public flagellation from Romy. I don't know whether to laugh or to cry. Actually, I d...

Hm, I did not realize that that it was a preamp. I thought that
it was a hybrid power amp. In preamp the Y10 probably might sit at lower
voltage. I have no idea how can they talk about preamp and do not talk about
what output impedance it has....

I heard back from Lamms about the relay pulses. They suggested I bias the amps again and then Lamms went silent when that didn't work. But the problem disappeared when I got around to replacing the 12AX7s that came with the amps.&nbs...

Hi Jarek,Apologies for missing your post.To answer your questions:(1) Yes and no. I've bundled the preamp into its new chassis (that I made from scratch) and it does not sound as good as before. There is a grounding problem with the new installatio...

So, I have been looking into suitable valves to base a preamplifer around that are suitable for driving the DSET's. The pre must have a broad bandwidth, low output impedance, some current drive, and not be prone too easily to microphony. Oh, and pr...
