I made some changes upstream from my amp and now I'm going through different tubes again. I don't think I've mentioned my current input tube before. I really enjoy the Raytheon 6f8g. If the RCA 6sn7 sounds thick, the sylvania 6sl7w brown base sounds vivid, and the tall Sylvania 7n7 sounds warm, I guess I'd call the R 6f8g solid. Everything has weight and feels locked in.
I went back and tried the new Tungsol 7581a tubes and I thought they sounded kind of brittle. The new Gold Lion KT66 sounds really good with the R 6f8g. Maybe it's a bit "hi-fi" sounding, neutral instead off warm. For the warmth I'll pop the 6ar6 back in.
In wallet weight reducing news I sprung for a quad of the GEC E3375 tubes. They have the same connections of the EL38 but have the same plates and general construction of the legendary GEC KT77. I can't afford the GEC KT88, KT66, or KT77 so this purchase will be as close as I'll ever get to those. If nothing else it'll be nice to have a GEC tube in my collection lol.
