A quintuplet of cryogenically treated NOS Telefunken long plate 12AX7 tubes from the Berlin factory (B nf 01). All five having same date code and testing near double or over double the nominal acceptable number, 875, per my calibrated Hickok 539b. Purchased years ago for my Marantz Model 7 preamp, but never used. Silkscreen lettering/numbering excellent, with modest rubbing. Test results shown below. I have documented the embossed numbering between the pins for each tube. Sold as pictured and described. Original Telefunken sleeve, old replacement valve boxes.
