Jim, what is operational point of the 6E5P, what it drivers (how it coupled) and how do you bias the 5E5P? BTW, the clipping at the bottom is very good, very symmetrical. Try to measure which stage clips first: the driver or the output stage. One m...

Dear Romy,
Obviously it is impossible to convince you upon the frequency response of our transformers and in any case that is fine with me since everybody is entitled to its own assumptions and opinions and this is not bad at all, on the cont...

Paul, would you think 6336 will be more stable/predictable?Have you had any experience with it?30H: sorry, forgot to mention that the PP pair is autobiasedwith a common 900R resistor...EL34: indeed it's a very popular tube for driving Stax electrosta...

I'm going to try and build a Melquiades type amplifier (with some help from friends) following the advice given above to make it as simple as possible. I could spend more money for "different" transformer, but I will ask you for advice on...

and not very encouraging. The set up was as follows: a Lowther ex4 playing from ~12k down in a big ~100Hz tratrix. A Murata up on top, and a 15" Beyma on the bottom. The Beyma is in an Onken so the results may not be fully indicative of performance i...

Could anyone here get through the whole spiel? I found it rough going at first and then impossible once I saw the pictures of the product. The immediate sense I could not escape is that it is (at this point, anyway) more about a "total marketing pl...

Yes, I totally agree. In my old place, I had the Druids working in FR with the Berning Siegfried 300B, and they sounded exactly as you say.But I'm hoping that the Berning will cope better driving the Druids with a high-pass filter set to around 150Hz...

Either my ears have gone bad or I must be the luckiest user of pure power regenerators. Have been using three for four months now and am still bowled over the improvement in my system. No matter what time of day I listen it sounds superb, but I do no...

Thanks for your thoughts.What is the TESLA battery? You mean the monster thing they use in the cars? Now that would be one hell of a battery!If I do it i will get SLA SGMs - gigantic LiFePo makes me nervous - I try to stay as far away as I can from...

Well done that man.

In case there's any confusion, it was the Avatons in Munich (and not the Animas). I took a good listen to them on Friday, and wasn't overly impressed. I spent a long time there yesterday though and thought they sounded better than anything else I'd h...

Years ago, when I visited the Cogent guys, Rich was working on one of their big drivers. The diaphragm was big and even thick and heavy, as compression driver diaphragms go. Of course they used 300B amps, and the bottom end had the "sewer pipe" type ...
|

Yeah, so the closeness of the grids results in a higher current gain. So what? What is the relationship between gain and sonics? Are you saying that all high gm tubes sound better than low gm tubes? And does that include 300B ...

[quote user="Romy the Cat"]In fact you can model the great sound for very, very small rooms (headphones) with existing direct radiators, have great result and no need for horns.[/quote]Yes, this is exactly what I've attempted to do. The rooms in the ...

Romy Hi, Raplh uses a 300b push pull, but the power supplies are massive, parts alone 15K Euros, each channel has a separate supply, the pre-amp again two massive power supplies , he prefers to use eight of the horn loaded bass bins, although I...

Scott, my apologize, but issue of low-power does not have any relationship to the problems, you have described. The problems could be located in the following areas:- high output impedance of the last cascade, and amplifier in g...

[quote user="Paul S"]Merlin, won't you at least put your amp in some sort of meaningful context, because it is a waste to continue this thread if you just treat it like a pissing contest.What speakers do you use? What sources, etc?&nb...

Well, I thought there was a lot of this going on all along, but that we just haven't come up with much that is "universal" in the usual, "what do you recommend?" sense yet? Maybe this is because one person's Cu PIO is another person's...

I have had similar impressions to other speakers using these drivers. For example I found the top of the line Avalon Eidolon diamond to be similarly colorless and lifeless. Also a pair of Vaic speakers (designed by the guy from Lumenwhite...

Hi to everybody,I have used those caps: teflon V-caps, AN copper, Jensen copper, Siemens at the signal path of a tube power amplifier (300b SE) application. V-caps are technically very good, very clear, less microphonics, but missing s...

Hi,
I have a phono stage from the Korean company Silvaweld that uses the 5651 tube in the power supply as a voltage reference. It also is using a Russian 6C19Pi tube along with EF86 pentode as the high voltage regulator. The rectifier is...

Hello Gera,First thing I would do is get rid of the active Xover, in my experience they mud everything up. preamps are very important and this is like a double preamp with a lot of gain stages. For bass you can maybe use it. I use a separate Xover...
|

Novygera:If you have a transformer where the impedance primary-to-secondary is 5K:8, it means the turns ratio is (5000/8)½ = 625½ = 25. This is the ratio by which the voltage is stepped down and the current stepped up in going from the tube to the s...

The weak bass of low-power SET amps is well known. I don't think anyone would disagree.Some reasons:Simple low power, especially with 93db speakers (try with 106db like Yorkville LS1208 horn subwoofer it might be different).SE output transformers hav...

My experience has been that tubes that run quiet and quiet down quickly and "properly" when tapped are almost always quiet with respect to self-noise and/or microphonics in use, apart from low level phono use. And most of my tubes tha...

Hi Romy,Great site, got lost here for a while now searching WE13a after building a WE91a 300B set, quess have to reconsider sell and wil look in to the Melq's for the near future... Also it even got me a little in to horns...For now i have a question...
