Hantra et al,
I think it's simply economics. Us audio crazed folks are the only ones needing much of tube stuff, so the demand ain't huge; so we get few (new tube) supply options in turn.
I heard once there were only 200,000 two channel audiophiles in the US...a number than has changed remarkably little in many years (if anything, may be less these days with video, surround sound as competition for your listening time). Of the 200,000, not all listen with tube equipment.
Worldwide, there may be less than 500,000 two channel enthusiasts that give a rats butt about tubes...
I own a Saab. I like it, but they've never made more than 125,000 cars any year. The list of after market parts (performacnce primarily) is very small...as it should be because the cars out there are relatively small in number (don't mention Porshe being smaller, that's a different type of car entirely
) If someone could make a serious buck making Saab aftermarket performance parts, it would exist.
Law of supply and demand at work.
BTW - I like the new Sovvie 6922's better than more expensive old Sovvie 'Rocket' 6H23's..and better than some other NOS 6922's heard, too.
