What do you know about 12BZ7's, my man?  I got a bunch of these on a deal, because they have the same gain with twice the g and twice the gm of a 12AX; they looked like they could drive the RIAA from Hell.

I have heard that:
They are wildly variable in their characteristics, example-to-example (including in the same envelope),
They have a very short service lifetime, and then go hideously microphonic,
They tend to noise,
Other horrors.

Ever fool (I mean experiment) with any of these?
