- Fine tubes produced at the famous Blackburn UK Factory, and among the most sought-after EL34s in the world, early Mullard "X" Code EL34s are known for their warm liquid mid-range and syrupy overdrive in guitar and audio amps.

- They have a full bass and a nice high-end that is slightly rolled-off.

- The earliest and best examples have the codes X1 + a Letter on the bottom of the tube, followed by "B+NUMBER+LETTER+NUMBER" (e.g. X1H, B1H4). These command high prices since no tubes on earth can match their unique and phenomenal sound, and they are very rare nowadays.
Later versions have X2, X3 and X4 codes. These are still very fine Blackburn tubes with similar construction.

- Mullard EL34s do very well in Vintage and Modern Marshall amps and Boutique clones.

- They give a great Classic Rock tone that can't be beat.

- Nice warm crunch.

- Many audiophiles go crazy for these tubes as well, because they produce vocals with stunning realism.

- You can recognize some of these tubes by the dark "getter splotches" on the inside of the glass.

- Not all Mullards have these markings, however, sometimes these tubes were rebranded under logos such as Amperex, Philips, Valvo, RTC, RCA, GE, Solus and so on.
