MESA BOOGIE SPAX7-A Preamp Tube / Valve 750151F

£20.83 Ex Tax

The Mesa SPAX7 preamp tube is a premium-grade 12AX7 that possesses an even higher standard of overall performance due to its incredibly low sensitivity to microphonic noise. This is the ultimate preamp tube to use in critical gain-stage applications, particularly in first stage/input positions or other high-gain stages in the preamp tube string.

These tubes are selected during Mesa’s 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, further stabilizing the tube and reducing external interference and noise. Mesa SPAX7s deliver the lowest noise-floor for the highest-gain output. While not required for optimum performance, SPAX7s are a great tube to have on hand as spares and for any applications where the absolute lowest noise-floor and low-microphonic response is needed.
