Sovtek EL84 Matched Power Tubes Hard Duet

EL84 Matched Power Tubes

The Sovtek EL84 series of power tubes produce an unbeatable smooth, warm, distortion. Excellent replacements in vintage VOX AC-30's and the like, our EL84's are used by Fender, Crate, and Peavey. These are Sovtek EL84 tubes in platinum matched sets. Their platinum matching process consists of a 24-hour tube burn-in period followed by a bias (plate) current measurement in milliamps. Soft, medium, and hard style descriptions refer to break up modes of the tube for an overdriven guitar signal. Soft-rated tubes break up easier and earlier, yielding a heavier, harder distortion. Hard-rated tubes however will be cleaner, while medium-rated tubes fall in between.
