Amp Guru Andy Ruhl's comments:
This is a very nice tube, with quality in construction you'd expect from Svetlana. The tone is a little more bottom endy compared to the Siemens EL34 and the Sovtek EL34WXT. These work particularly nice in combos where you need the extra bass and not quite as much high end. But pumped through a 4x12 of Celestions, they are very, very nice. These are the only EL34's I'm stocking right now, although I can get others. You owe it to yourself to try these before you search out some really expensive NOS ones! Here's my take on EL34's: They belong in Marshalls! Some people like the way that they sound in Fenders and I'll give them that. But the reason why Fenders sound like Fenders has a lot to do with the 6L6's. Besides, installing EL34's in your Fender (which requires mods by the way) will put extra strain on your power transformer due to increased filament draw. There's no guarantee that your power transformer will survive!
