Update: this is finally published!! Link
It’s been a long time since one of these last appeared. Although Enjoythemusic, TNT, and 6moons have posted 300B tube comparos in the past, they happened in 2001, 2004, and 2008, respectively. Richard Foster’s excellent articles in hi-fi+ were….10 years ago(!). Overall quality of Chinese and Russian tubes has improved consistently since that time, and here at Wall of Sound we think it’s an appropriate time to update the knowledge base. We still think the 300B type is one of the finest power triodes available. And for these listening tests we’ll have on hand at least two excellent single-ended stereo amplifiers.
So we’re pleased and excited to accept the challenge, and we will publish a “2015 300B Shootout”, by the end of July. So far we have eight entrants, with huge thanks to our sponsor (and neighbour), Thetubestore.com :
By place of origin we have 2 Russian pair, 5 Chinese (2 of which are premium grade), and 1 Slovak.

To say the least, we’re looking forward to hearing and commenting on all of these tubes. And possible a few others.
