Mullard CV4004 12AX7 Preamp Tube
The Mullard CV4004 12AX7 Preamp Tube delivers a large sound stage with excellent detail. Factory selected for low noise and minimum microphonics.
The CV4004/12AX7 is a high gain, low noise valve with a short plate structure for reduced microphonics. The Mullard CV4004 is excellent for use in high gain Marshall pre-amplifier circuits where noise and microphonics can be a problem.
A definite recommendation for guitar amps. The CV4004 is a version of 12ax7, ECC83 and 7025, and performs well wherever a 12ax7 can be used.
