in Search of the Perfect 300B Tube

I guess the only true 300B is the pre-1988 Western Electric 300B, all the newer versions are probably best described as 300B compatible, as they differ in materials, structures etc.

Die 300B wird oft als Königin der Trioden bezeichnet.

Und meiner Begeisterung über das einfache Umstecken von 300B auf 2A3 kann ich gar nicht genug Ausdruck verleihen. Wie immer Du diese Möglichkeit auch geschafft hast, es funtioniert perfekt! Hilfreich ist dabei, daß Du die beiden Heizsymmetrierungen der 45er und der 300B/2A3 auf die Frontplatte gelegt hast, so daß der Wechsel auch für Technikdeppen wie mich nicht länger als 1 Minute dauert.

There was a post on Tubes Asylum that the weaknesses I was attributing to the amplifier were probably due to the installed 300B tubes. So I changed them. There you are: invalid review. (I won't even tell you about power cords.) Moving along, then, here are the substitutes: WE300B, VV300B, and Sophia 300B. This is the absolutely perfect Goldilocks and the Three Bears story. Remember it? Goldilocks is lost in the woods and finds a cottage. Three bears live in the cottage, but they are not home at the moment. (I always thought that was a little too convenient for Goldilocks, for she surely would have been eaten, but it’s a children’s story and allowances must be made.) She goes inside and finds three bowls of porridge, and being hungry, helps herself. After sating her appetite, she goes upstairs for a nap and tries out the three beds she finds there.

OK folks – here’s the tube part. The Western Electrics were too soft, having indistinct bass and highs that did not reveal a significant amount of information. GREAT mids; poor bass and little air and extension on top. The VV tubes were too hard, and while their bass was much deeper and tighter than the WE tubes, the upper midrange had some stridency and hardness that made their use in this amplifier a combination to avoid. So that leaves the Sophias. I’ve heard that JJ makes a good 300B, and Cary is now offering a 300B under their name. These were not tried. The Sophia Meshplate 300Bs, to return to the nap-time adventures of Goldilocks, were just right. Let me be clear. I do not mean that the Sophias were the best overall compromise, or did the least wrong of the three tubes, or simply won a 3-way shoot out. The Cary 300SEI partnered with Sophia 300B tubes offered musical bliss. The pairing had excellent bass (for a tube amp), the wonderful midrange of the WEs, and airy and extended highs that were as close to perfect as I could want.
