amperex 6922 pinched waist

You're paying for the story, not the tube.

Best performing 6DJ8-oids I've tried have no collector value and (last time I bought them) went for $8 a pop.

I heard Amperex, Siemens, Telefunken, etc and the best one E88CCC that I heard with a lot of difference is this military russian graved 6H23n-EB

At one point I had (might still - lost in the stash somewhere 😀 ) a number of Amperex 7044 with pinched waist - quite deliberate, but rather strange looking. Appears to be intended to reduce microphonics, whether or not it works is another question.
