Electro Harmonix 6922 pre-amp tubes

I can't imagine why the gold pin would sound any better, if you do have to slots that are know to be the most influential on the sound, that might very well be a good place to paly with some NOS, I would recommend Amperex 6dj8, 6922, or 7308s (I think that is the right number).

The same tube is always going to sound different in a different circuit. It depends on how that tube is implemented within the piece of gear.

I had the EH tubes sound great in a phono stage, but horrible in a DAC.

The best sounding "new production" 6922 tubes that I have tried are the JJ Tesla. These still aren't as good as what a NOS tube can do.

In my amps/pres the JJ were the best sounding Current Production as well.

What preamp? If it's the least be "hard" on the tubes, the JJ's will be a nightmare. I will agree that they are the best sounding current production, but they have a horrible failure rate if pushed in the slightest.

The EH 6922's are my current production tube of choice in my Bottlehead phono preamp although I prefer some NOS Tesla's from the 70's with some cartriges.

Has anyone compared the EH to Sovtek 6922s? i will need to be replacing the 8 6922s in my phonostage at some point, and dont want to go the NOS route.
