For sale is one perfectly matched pair of genuine EL34 / 6CA7 made by EI Nis tube factory in Yugoslavia in 90s.
They are from service packaging of 50 pieces in original yellow boxes for every single tube. Genuine triple mica, with dual OO getter. Mica spacers with 12 support points, stapled plates, three holes on plates, black base with central hole in the guiding pin like vintage Mullards.
I have few 50 pcs service packagings 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 EI EL34 with perfect prints and the same etched codes today, be fast and take this opportunity while they are still in stock!!!
These tubes were sold under Siemens, Philips and few other brands in 90s, when West European plants were closed and there were still high demand for these quality EL34 / 6CA7.
