Genalex Gold Lion ECC83/B759 (12AX7) dual triode preamp tube with gold pins. Original Genalex Gold Lion ECC83/B759 tubes are considered among the best 12AX7 types ever made. They are hard to find and when they are available, they are expensive. They exhibit a large detailed soundstage that is sought after by discerning audiophiles who demand the highest quality sound. The reissue Genalex Gold Lion ECC83/B759 recreates the sound signature of the original. This tube features balanced sections and gold plated pins.
