Αudio tubes

Νήμα για τις λυχνίες ενίσχυσης και ανόρθωσης, παλαιάς παράγωγης και νέας εσοδείας.
It has been a bit quiet about Elrog during the recent months and I would like to give an update about the state of the company and the future. I have some bad and some good news. The bad news is that due to various reasons Elrog struggled financially and was forced to enter the insolvency process. The good news is that Elrog tubes will continue to be produced. I founded a new company which acquired all assets and machines of Elrog. This company will continue the manufacturing and distribution of Elrog branded tubes.

I think the 1-year warranty on the Sophia ELectric Royal Princess may make up for the gap. But while I do really like the full-frequency performance of the Royal, boy-howdy, that Takatsuki was stunning. If you’re into jazz, female vocals, and small arrangement pieces — otherwise known as the “audiophile audio diet” — to the exclusion of everything else, this tube is a show stopper.
In my particular situation, having both Takatsuki TA-300B and the Western Electric 300B, the type of music to which I am listening dictates which set of tubes go in the Kegons. For classical and jazz, I find that I prefer the Western Electric tubes in my system, but for rock, the Takatsuki’s edge out the Western Electric’s. Both are excellent, and in a different amplifier or for someone with somewhat different tastes, this might be the ticket. The Takatsuki’s are the only tube which I would consider using in place of the Western Electric 300B.
JJ Electronic began the development and production of vacuum tubes in 1994. Since that time, we have successfully introduced 17 more tubes into production. In 1999 we began the production of tube amplifiers. The first model was the JJ322, a class A amplifier, powered by four JJ Electronic 300B triodes. Today, we manufacture four power amplifier and two preamplifier models. All these products have been safety certified for the use around the world. Also in 1999, we introduced the production of electrolytic capacitors. Three years later, we started production of polypropylene capacitors. These capacitors received certification from international test authorities. We started our company with about 700 sq meter production facilities; today JJ Electronic owns more than 12000 sq meters of production floor.

For use in Single Ended amplifiers, the 300B-XLS is the best choice, since with those amplifiers good sound is coming from the right use of the tube, not over stressing the tube. The right use means, the tube should not be working at it's maximum electrical performance. Here we think the 300B-XLS is at it's right place, taking advantage of the higher electrical reserve this tube has. The 300B-XLS will reproduce the required loudness with more ease than the standard 300B. The result is a more transparent sound picture at low or medium volume, while at higher volume, the dynamics of the original recording will stay unaffected.
Another purpose of the EML 300B-XLS is to get more power, than is possible with standard 300B tubes. This can only be done when you have the possibility to adjust the settings of the amplifier. If you increase the plate current of the tube ABOVE the standard 300B specifications, something very special will happen. The tube will now move to a part of the curves where it has a lower plate resistance. This is a specialty of the 300B-XLS. This will give a better damping factor of the bass and mid range loudspeakers, resulting in a more natural sound.
