We are an authorized dealer for New Sensor products including Sovtek, Electro-Harmonix, Mullard, Tung-Sol and Genalex. We sell A grade quality stock, not factory seconds like many other sellers. 

You may notice other sellers listings these at a lower price. New Sensor increased the price on all of their tubes this year. Anyone selling their tubes below market value is selling old stock that will run out at that price or B-stock. These are fresh tubes.

One Brand New in Box Mullard Reissue CV4004 /12AX7 Vacuum Tube

There are two versions of the reissue Mullard 12AX7. This version is better suited for guitar amplifiers. This tube was molded after the British military CV4004. CV4004 is the military code for the 12AX7 and was designed to be more rugged. The short plate design cuts down on noise and microphonics which is especially important for this tube as these tend to have high gain. These are sweet sounding beauties that rival the originals.

Double-tested for Gm, Gain and Shorts at real world voltages on a Maxi-Matcher tube tester. As well as checked for Gas and Leaks on a vintage tube tester. Guaranteed to test at or above new / nos values.
