For sale is one perfectly matched quad (4 tubes) of genuine EL509 / EL519 / 6KG6A made by EI Nis Yugoslavia under Philips licence in 1978, ADW codes.
EL509 printed on each tube, but they have genuine ADW etched code and they are EL519 indeed.
These tubes are specially selected for export without EI logo printed on each tube, you could see them rebranded Philips, Telefunken, Valvo, Tesla, RSD, Tungsram or Siemens
They are from service packagings of 50 pcs in original individual boxes for every single tube. All four tubes are matched within 5% (platinum pair). True triple mica version (early Philips construction, much much better than later dual mica versions).
They are the same dates and exactly the same batch! Why this is so important?!? Because EI has bought materials from few suppliers and it could happen that you can find the same construction type, visually identical, but made from different materials. Those tubes will not change characteristics in the same way in your amplifier like ones from the same batch. These ones will be platinum quad for years ...
These tubes are perfect replacement tubes for EAR861 / EAR859 amplifiers.
