Groove Tubes Gold Series GT-12AT7 Preamp Tube

Tested under extreme listening conditions and guaranteed to be free of excess noise and microphonic ring.

The Groove Tubes GT-12AT7 preamp tube is designed for outstanding and consistent performance when mixing and matching in order to get a signature tone from your amp. Made with a durable design that can be used as a phase splitter or driver tube, the 12AT7 is ideal for use in vibrato or reverb circuits where consistent, high-output power is desired. It can also sub for a 12AX7 to lower gain and produce a slightly warmer tone.
