Most of you have more experience with 6DJ8s than I. But I recently started using a Moscode power amp (tube input, Mosfet output). The 6DJ8s were nameless generic Russian, not even a "brand". I thought surely I could improve on them.
I had a pair of NOS American-made gold-pin Amperex. According to some online discussions, it was "the best" 6DJ8 ever made. Even if that’s just bs, I figured it had to be good, certainly better than no-name Russians.
They weren’t nearly as good — big disappointment. The difference wasn’t minor: the Russians were better in every respect, and I put them back in.
No break-in time on the Amperex, which might be a factor... but the gap it would have to close seems insurmountable.
I just wish those Russians did have a name, I’d buy a lot more.
