Our highest-gain preamp tube, this tube has a huge amount of gain, with terrific output that makes it a great choice for driving modern complex high-gain circuits. It has a relatively high quality variance, with a tight, strong relatively bright tone, that can really liven up a weak or tired old vintage amp or a new amp with grade-quality tubes.
