They were promised there would be no math!The demonization of feedback is very amusing, and very unfortunate. The measurements are unequivocal, and the math can be followed by a person who remembers high-school algebra,

As a physics professor, boy, I've heard that phrase from students...They were promised there would be no math!
When I put Soviet tubes into my E6, instead of discarding the aluminum cases, I decided to use them as RF/EMF blocking hats for the tubes (tin-foil hats).Precisely. Leaving them in place would have solved or at least reduced the effects of both key problems with this device: microphonics and RFI susceptibility. Using better tubes would have been nice, too.

I've seen the video on removing the cans before. My question is, what is required to get the cans to fit into the E6 as you have done? Did you cut off "part" of the cans?After reading through the Audiokarma thread on the E6, I ordered the Soviet tubes off of Ebay and a pipe cutter off of Amazon that can accommodate 1.25” diameter. I just had to mark the new tubes with a marker before I cut them out so that I could easily orient them into the sockets. The Youtube video below shows another method to cut the shells. Truthfully, I was happy with the Chinese tubes that came with mine; I think I got lucky. Initially, they had obvious bass roll-off, but that went away after a couple of days. To me, the most obvious difference with the Soviet tubes was that they didn’t have that initial bass roll-off. There were reports that the Soviet tubes were less likely to be microphonic, but I never had those issues with the stock tubes.
Sorry. I misunderstood what you were asking. I didn’t do anything. The shells are literally just resting upside down on the case of the E6. The tops of the shells were cut off to get the tubes out and then I just flipped them over and used them as hats. I sanded the edges of the shells where I cut them because they were pretty sharp.I've seen the video on removing the cans before.

In fact they don't.Then pray tell me; why is it that two (or more) identically measuring amps most often sound different from one another?
Failure to accurately level match.Then pray tell me; why is it that two (or more) identically measuring amps most often sound different from one another?
NOT to suggest that the E6 is good, but I reckon that to say "impossible to use" is hyperbole.I have one but it's not good, The tube harmonics make it impossible to use.
You're answer kills me, and proves my point.Failure to accurately level match.
Failure to listen ears only without using eyes.
Failure to operate inside power envelope.
Tell me - why did you bother to create an account here? Just to come and tell us how wrong we all are? How far do you think that is going to get you? Every word you write tells us how little you understand about audio electronics.
These things have been tested, but there are a lot of execution variations of the same circuit inside. I have an older version of the same, and it's a distortion box, and not even the good type of distortion. If you like it, it's ok, but don't claim that it's good on hifi (= high fidelity) or that it can replace a real engineered tube amp. It's a ic preamp with a tube buffer that is badly executed, and it mainly generates general distortion, not clean 2nd and 3th harmonic distortion like the better coloured tube (pre)amps does.You're answer kills me, and proves my point.
Instead of eyeing the ball, you went for the man. As I knew you would.
I'm dying to hear the names of all the wonderfull world class amps you've created with all your brilliant knowledge. Don't be shy!
