No idea, I've heard of a bile pump though.

I've seen machine translation use the world "gallbladder" in place of "vacuum tube" so go figure.

It would leave a bitter aftertaste after a listen, with a name like that. What are those little 7-pin tubes?

Rather brilliantly, from one of the comments/ reviews

"note favourably changes especially in high frequencies, which ceased to be so marked or metallic and the low frequencies and above all stockings were strengthened."

So one for all the hosiery wearers out there.

Not sure what the rules are here re: posting links to other audio sites; there is a very lengthy thread about these units on Audiokarma, with more info than you wanna know.

I can PM a link if direct links are an issue
