Mesa Boogie SPAX7 Tube

MESA SPAX7 preamp tubes are top - notch 12AX7 tubes. They offer an outstanding overall performance because of their extremely low sensitivity to microphonic noise. Ideal for critical gain stage applications, especially in the first stage/input positions or other high - gain stages of the preamp tube string. These tubes go through a strict 12AX7 testing process. When they prove to be more stable and quieter in extreme high - gain situations, they get a shrink - wrap shielding. This further stabilizes the tube and cuts down external interference and noise. MESA SPAX7s give the lowest noise floor for the highest gain output. While not essential for optimal performance, they're great spares and perfect for any setup needing the lowest noise floor and low - microphonic response. PLU: 750151F

Using your Mesa Boogie SPAX7 Tube is quite straightforward. Just install it in the appropriate position in your preamp, especially in critical gain stages like the first stage or high - gain areas. When handling the tube, make sure to do it gently to avoid any physical damage. Keep it away from extreme temperatures and humidity, as these can affect its performance. Regularly check the tube for any signs of damage or wear. If you notice any issues like unusual noise or decreased performance, it might be time to replace it. Although these tubes are very stable, having a spare on hand is always a good idea, especially for important gigs or recording sessions.
