We have a small batch of NOS Mullard made Xf4 EL34 tubes. These legendary tubes were made at the Blackburn factory in Great Britain during the 1960s. They were packaged for Philips and are in original boxes. The logos marked on the tubes were for their French subsidiary RTC (Radiotechnique). The construction details include stapled plates and a single "halo" getter.

From Vacuum Tube Valley: "An excellent sounding tube with outstanding performance in our system. Dynamic range and frequency extension were exceptional and all other categories were rated as one of the best."  They also noted, great frequency extension, musicality, and dimensionality.
