Platinum matched pair (2 tubes) of rare Mullard Blackburn EL34 / 6CA7 Xf4 type, rebranded Philips in genuine yellow Philips boxes.
I had few 100 pcs boxes of these gems, so all pairs I offer for sale are perfectly matched, within 2% or less.
Two slots on plates, four support points on both spacers, folded plates (stapled), copper grid posts, black base!
They are made in Mullard Blackburn tube plant, and etched codes the same. The codes are clearly visible on photos Xf4 B9K4.
