We only have three pieces remaining of Mullard CV4003. All 3 pcs have balanced sections.
One of the sweetest highest quality 12AU7’s, the Mullard CV4003 is a Military spec, boxed anode, super high quality tube! Recommended for Hi-Fi and for getting that sweet spot and usable gain in those tube based overdrive pedals!! An Amazing tube! This is a suitable replacement for any 12AU7 tube type.
