Elrog 300b news

In electronics , the B is a directly-heated power triode vacuum tube with a four-pin base, introduced in by Western Electric to amplify telephone signals. It measures 6. In the s it started to be used increasingly by audiophiles in home audio equipment. The B has good linearity, low noise and good reliability; it is often used in single-ended triode SET audio amplifiers of about eight watts output; a push-pull pair can output 20 watts.

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. But while I do really like the full-frequency performance of the Royal, boy-howdy, that Takatsuki was stunning. In my particular situation, having both Takatsuki TAB and the Western Electric B, the type of music to which I am listening dictates which set of tubes go in the Kegons.

Both are excellent, and in a different amplifier or for someone with somewhat different tastes, this might be the ticket. JJ Electronic began the development and production of vacuum tubes in Since that time, we have successfully introduced 17 more tubes into production. In we began the production of tube amplifiers. 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 , 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 sq meter production facilities; today JJ Electronic owns more than sq meters of production floor. For use in Single Ended amplifiers, the B-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 B-XLS is at it's right place, taking advantage of the higher electrical reserve this tube has. 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.

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 B 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 B-XLS.

This will give a better damping factor of the bass and mid range loudspeakers, resulting in a more natural sound.

Looking for someone who may be interested in trading B tubes. I have an excellent pair of Elrog B's with a year of part time use.

Once production is confirmed, the order will require a deposit with the expected fulfillment date announced. The magic of the original were the high frequency heaters, if EC can confirm the same are found here then it may be a good buy. So… Ok. Sounds like someone has a serious grudge against SBAF? Not that I care, honestly. I only care about facts and empirical observations. Why launch a new amp with just a price tag? Still, it seems that is just the way of top end tube amps nowadays - the glass costs more than the iron they get plugged into.

I seem to chronically underestimate a lot of things. This was a fun assignment, but also tedious. The bottom line? That said, each tube had its strong points, and I tried to take a somewhat objective approach to the comparison work.
