One perfectly matched quad of genuine EL34 / 6CA7 made by Mullard, Blackburn in 1975, Xf3 codes. 


They are rebranded Siemens (Siemens has never made any EL34!), NOS NIB, in original Siemens boxes. 
Top mica spacer with 10 support points, folded plates (stapled), two slots on plates, black base with central hole in guiding pin. 


I had a few dozen of these tubes (all the same date codes!!!), and all quads I have are carefully tested and matched by plate current on my Metrix U61-B tester. Due to big number of tested tubes, they are matched within 5% or less!!! These are very strong examples, selected from big number of the same batch tubes!

It's really hard to find four practically exact genuine NOS Mullard EL34 with perfect prints and the same etched codes today, be fast and take this opportunity while they are still in stock!!!












This is a private listing and I do not give a warranty about the quality of the valves, and I do not accept returns. These valves are carefully matched and they are 100% in perfect working condition, I simply can not take responsibility for some users who do not know how to change tubes in their amplifiers.
