Mullard 12AX7 Preamp Vacuum Tube, Single
The Mullard 12AX7 / CV4004 Dual Triode Preamp Tube is made in Russa. The CV4004/12AX7 is a high gain, low noise valve with a short plate structure for reduced microphonics. Excellent for use in high gain Marshall pre-amplifier circuits where noise and microphonics can be a problem. Great for guitar amps.
Premium high gain Twin Triode ideal for use in HiFi preamplifiers. Replicates the sound signature of the large plate Mullard ECC83 tubes that were popular in the 1960s and 1970s.
