EL34 TSL100/TSL122/DSL100/JTM100, Artiste 2059 Valve kit for Marshall amplifiers
EL34 quad factory matched to within 1mA anode current. “I find the Shuguang EL34-B to be a very warm sounding tube with a magic midrange. Highs are excellent, but not to sharp. They are much louder and CLEARER then the other tubes I've tried.
