The mother of the 300B is the 300A, both designed by Western Electric.ĭrawing of Western Electric 300A / 300B tubeīefore the 300B, there was the 300A, which had a different position of the Bajonet pin on the socket. IF THERE IS ANYTHING WRONG WITH THE ABOVE 300B INFORMATION PLEASE LET ME This note reflects the situation of July 2016. For this reason it is not listed in the "300B Factory" list. So it is a matter of taste if you still want to call this a 300B, but personally, I say no. This will have a drawback on the tube curves, and as a logic result, such tubes can not have the same dynamic parameters at the same variety of operating points which is possible with a Western Electric 300B. The ELROG has a tungsten heater, which is optically nice, but this technology has by default lower emission than the (red glowing) Barium Heaters of Western Electric 300B. Of course there is no obligation for this, but I just want to express here my opinion. With all respect to makers, and the nice appearance of those tubes, to my personal opinion this tube is not fully in accordance in all details with the historical Western Electric data sheet. The German company ELROG makes a tube they call 300B. We have no other thing to say, we call this faked mesh. The Chinese factories produce only an optical illusion of mesh tubes. These were introduced by Emission Labs, and there is no other factory that makes them as we write here Febr. AVVT: Brands used: Audio Note at first.TJANJIN Factory, with links to SHUGUANG.Used brand names are: Sovtek + Electro Harmonix Emission Labs: Genuine brand with own production.The never ending list of Chinese phantasy names are all SHUGUANG made.SHUGUANG occaisionally sells under it's owm brand name, but doesn't seem to like that.From what I know, I can tell the following: Specially in China, this is a very dynamic scene, and it is not possible to be up to date here. There are several brands on the market, which are made in one of the factories above here. This is the list of FACTORIES that produce 300B tubes. There is simply no other way to put it and 1000 more words would not tell you more than that. If you desire true realism, then here it is.UNLISTED 300B TUBES: For brands that are only trade names, we do not list that here, because this is 300B factory list. The result is an amplifier which presents more than just tonality or the harmonic structure it is the weight, complexity and gestalt of aurally having the instrument within your listening room. Taking nearly 100 hours each to produce by highly skilled personnel with many years of experience. and for good reason! Here is the legend of handcraftsmanship, many pounds of hand wound silver transformers and a generous sprinkling of exotic parts all wrapped into a single chassis. Many audiophiles around the world, rightly, consider it one of the 'Holy Grails' of audio. Utilising a combination of both copper and silver for the transformers, its performance is both unique and beguiling.Īh yes, the legendary Audio Note Ongaku. The TOMEI bridges the gap between the JINRO and the ONGAKU. The JINRO plays melodies with unsurpassed flow and momentum. Those who seek even more refinment and sheer power can enter the TOMEI or JINRO which share the same circuit design as the legendary ONGAKU. The overall sound if the JINRO is very subtly sweet, with a midrange that is a bit soft-timbrally, but not temporally-with an abundance of that often-noted-yet-never-explained "SET sound" that allows solo voices and instruments to stand musically and spatially proud of the rest of the mix.
#Buy audionote 300b tubes full
Naturally, warm, and full sounding, it can be upgraded with NOS tubes to take it pretty much any direction you like. This is the best way to bring 300B tubes into your system if you’re a prudent rather than self-indulgent audiophile. Meishu, Meishu Silver, Meishu Silver Signature, 9 watt SET, 300B based integrated amplifiers. THE SORO, 6L6G tube based integrated amplifiers come with a more robust and fuller presentation than the OTO. The best amplifier value in the Audio Note line. The OTO is satisfyingly full, dynamic, and clear, sounding and wonderfully informative through the midrange. Our range of integrated amplifiers starts with the OTO Push Pull or Single-ended, EL 84 based, integrated amps. The result is a truly startling level of naturalness, detail, and ease, something not found in audio equipment today. We create low power amps to be used with high efficiency loudspeakers. One route combines high power amplifiers with low efficiency loudspeakers. You could say there are two lines of sight in audio amplification. Audio Note electronics may be the key to the Audio Note sound.
