Yes, decoud, the 6e5p-GM70 is an easy amp but 6e5p is a hell of voltage driver and I do not feel that a single 6e5p will be able to drive GM70 into grid currents. If people use dead speakers and need a lot of power than use the ability of direct hea...

I bought those tweeters for Be Yamamura (second hand from Paul at Wembly Loudspeakers, in London) I also took Be to Heathrow Airport to take a plane to Brazil to install one of his truly superb VT4c stereo amps! It was the morning of a great wind ...

Yes, well - I wasn't really saying much; just a vague hypothesis. There is some tendency for lower Rp tubes, (and somewhat related) tubes with a certain harmonic structure, to sound more romantic, and hence impart that quality to music regardless of ...

Shame on you Romy, you took them all without leaving some for others!I am waiting for the shipment of these tubes, I only bought 3 to try it out in my amp. In the meantime, I am running my amp with the rest of these unknown qualities from Asia with f...

Well, I experienced the same exact phenomena with using different 2A3 tubes as you remember, which I do believe has to do with the mechanical harmonics in part.[/quote]
I do not remember that, it you wrote it then I mo...

(Romy feel free to move this post)[quote user="Paul S"]N-set, I understand you do not mean to hijack the thread with the Axiom, so I actually tried to make generic and/or thread-related observations. I don't know the 6E5P, but generic issues with sp...

[quote user="Paul S"] The 6N6Ps I bought are nothing "special" as far as I know, but they are all tested and to spec, according to the seller, so I will also replace my current 6N6Ps when the new (NOS) batch arrives, and I will note any changes in so...

I'm sure there are many bad implementations of the 845 and 211. Almost all of the commercially available ones are pretty mediocre. However I have heard good examples of both so I know it can be done. I've yet to hear an impressive 6C33 amp so it...

I have to say, I never gave it much thought, since, as you say, The Book says 5751s are an OK sub for 12AX7. I did realize that the gain was lower, but I obviously had a brain cramp in not interpolating the lower gain to "redistributed" global ...

Wise words that mirror my own renewed concerns, Romy.Any recommendations for a particular tester, anyone? The last time I put my hands on a tester to use it was in a drugstore, one of the many places you could find them back in the day when rad...

[quote user="Romy the Cat"]Got today a party of the 6C18C from 1960s, an interesting tube. The plate looks like 1/4 times larger and has no bridge between the halves. The 6C18C has even less plate impedance than 6C33C and it appears that it futures i...

I know that I ma a wacco, so extend patience while you read it.
I was cleaning my shelves and found a strong alnico magnet that left from my field-coil. Since the electromagnet driver project was over I was about to assemble the driver back and send...

[quote user="drdna"]You want a suggestion for a good 2A3? Get Ricardo Kron's (KR Audio Enterprises) KR 2A3. Very rugged, overbuilt. There is no comparison between this tube and all other 2A3's, and I tried many of them. The sound is more dynamic, the...

[quote user="drdna"] You are correct, though I believe the subwoofer covers only below 40 hz. [/quote] So??? [quote user="drdna"] This is coming from the same person who has built a 6-channel DSET? Anyway, it was more a thought about optimizing the o...

Romy, I have a very large collection of 45 triodes.... many brands and varying internal construction. From my humble viewpoint, here's some personal findings on the various types:- Globe 45 tubes... these are the earliest, mostly from RCA. There are...

Serge, it is a common misconception that the old Altec cinema/PA systems were lovingly built and installed with tubes or high-fidelity "music playback" in mind. In fact, they were meant to be LOUD and durable sound reinforcement tools, while maintai...

Romy:I would suggest not to store tubes under the bench in an actively used sauna. While the temperature alone will not affect them, the combination of heat and saturated humidity may lead to corrosion of the pins. Also many bottles are held to bas...

[quote user="jessie.dazzle"]Since renewing all tubes in both ML2s, over the period of about 3-5 minutes, the V2 bias on one of the amps cylcles between .27 and .33VDC. Is this behavior indicitive of a defective 6C33C?[/quote] That is not good. Try to...

Well, for $225/ea they'd better be good!So who is going to find out if disgruntled users can get their money back?I bought something from this bunch a while back and they were OK to deal with.EAT? Bad name for a tube."European" c...

I've found they're slovakian company and regarding the product description, they don't produce the valves, they just make a search and selection of the best current production tubes. So they charge a nice fee for that selection and testing. Not bad.I...

I like to stress a point that the mammals that write thier doodles for audio publication are not juts ignorant fools but also the cheap, low class, falseificators. No wonder that the audio manufacturing companies do employ the so-called reviewers as ...

I got a forwarded email today containing the Lamm Industry’s release notes about their new SET amplifiers.

I kind of was thinking…
If a good DHT is able to give a magnitude of Absolute Tone that IDHT is
not able then it might be good… But. I do not use Single-stage
Melquiades amp itself but it supplemented with my Injection Channel.
The Inject...

[quote user="cb"] Yes, it is imposable to have + 0.4V on the grid, 0.0V at input, with R5 resistor in place and the gas tubes outputting +150V and -150V. My apologies, I meant to say I have minus 4.4v on the grid with the inputs shorted. Then I...

Morricab,
I do not know the “truth” and what I said are pure my speculations based upon what I hear and what I measure.
Yes, Lamm drivers at 310mA quite hard but do not forget that his objectives, besides everything, were to get out of his SET max ...

[quote user="twogoodears"] Actually a N.O.S. EC-8020 "diamond" is worth EUR 500+ ea., an STC 3A7167M is fetching EUR 750+ ea. (I own one N.O.S. sampler with original carton box, bought by chance for cheap, years ago) and WE 437A is at "only" EUR ...
