Mesa Boogie SPAX7-A · Tube

Mesa Boogie SPAX7 preamp tubes, the top grade 12AX7 with an even higher standard of overall performance due to their incredibly high microphonic noise resistance. The ultimate preamp tube to use in critical gain stages, especially in first stage/input positions or high gain stages in the preamp tube chain. Selected by our rigorous 12AX7 testing process and when found to be substantially more stable and quiet in extreme high gain applications, they are fitted with a shrink-wrap shielding which further stabilises the tube and reduces external interference and noise. MESA SPAX7s deliver the lowest noise floor with the highest gain output. SPAX7s are a great tube to have as spares and for any applications where the absolute lowest noise microphonics are wanted.
