New set of four Mullard 12AX7/CV4004 tubes. These are difficult to find at a reasonable price, so this is an opportunity to obtain a world class tube at a price that won’t break the bank.
This new production Mullard tube is manufactured at their Xpo-Pul factory (also known as Reflektor) in Saratov, Russia.
CV4004/12AX7 Mullard 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.
