The Mullard name and trademark have been acquired by the New Sensor Corporation. New Sensor is an American corporation and since taking ownership of the Xpo-Pul factory (also known as Reflektor) in Saratov, Russia has been steadily improving the quality of current production tubes. Their reissue Mullard 12AX7 preamp audio tube sounds great in hifi tube audio preamps and amplifiers where it's low noise and smooth sound really shine. Vintage Marshall guitar tube amp owners also find them to sound great but at a fraction of the price of NOS Mullard preamp tubes. The reissue Mullard EL34 is New Sensor's remake of the famous XF2 Mullard EL34 power tube. Again, a great sounding tube but for much less money compared to NOS Mullard EL34 vacuum tubes. The reissue Mullard EL84 power output tube is another winner. For guitar players in need of a great overdriven tone in Vox amps the Mullard EL84 is a good bet.
