Hi Jim;Very interesting! Hmmm, have they got a webpage? I'd love to see some of their efforts online.
See the link below for a pic of my 6BM8. One of these days I'm going to upgrade the iron on it and see how much better it can sound - very good now but the $9 OPT's limit bass response a bit too much....
All the best,
Morse

Yes it is in Tokyo.... Here's one that use those 6BM8 amps (In cookie aluminum cans) to drive very small Fostex backloaded horns (dorm room speakers!) Another similar tube I like is the ECL86. Here's a Japanese link in English btw.Derick

6BM8 has gained popularity amongst Japanese DIY'ers who use it in the so-called "super-triode" configuration. The circuit uses the triode section of 6BM8 in the feedback loop of pentode section. The theory is that the whole thing then looks like a triode with very low Rp - hence the name Super Triode.
At least that's what is claimed by the guy who started it:
