Description Technical Specs
 
1960s Ei tubes were real fine and much better than the stuff produced in 1970s and 1980s. Ei produced ECC88/PCC88, EL84 etc with transfer of technology from Philips Holland.

Matched Pairs, Brand new, MINT NOS 1969 Ei EL84 Hex Plate tubes with etched kM4 revision. All tubes with the same date code of (semicircle with dot)9F for Nish Plant from former Yugoslavia. Construction is very similar to the Philips Hex plate design from Holland. Repacked in generic white boxes from bulk. We have seen the same tube with Amperex Globe logo, Siemens and various other labels.

Excellent tube for Guitar and Audio applications. Tested and matched on Top of the Line Calibrated Hickok 580 Lab Grade Tester recently calibrated by late Chris Haedt. Minimum 65% = 7000 mmhos for EL84 on this tester.

Matched Pair = $60. Select 2 for a Matched Quad.
