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.

Great replacement for TCL robot vacuum
Size: 20 PACK
Love that everything fits. Only issue are the little brushes they don’t fit the vacuum I have :(

Perfect replacements for the G30
I wanted to replace the filters in my old G30 more frequently, as it's still running like a champ. I figured keeping up on it more often would help prolong its life expectancy. So far, so good. The less expensive replacement parts definitely help me not get upset every time I want to replace something. All parts from this pack fit perfectly, and the price is reasonable enough to avoid pushing replacements to the very last minute—at least it did for me, lol.

Great product for money but pay attn to your model filters are different on newer models.
Size: 20 PACK
The rollers work great and fit nicely into my Euphy which turned out I have a early version of which means none of the filters don’t fit my Euphy unfortunately and I hadn’t payed attention to the filters I was looking to get a 2 pack of rollers, the filters look nice though like they would make a great seal with the plastic and seal around them. I won’t buy them again for sure though for obvious reasons. Euphy is so much quieter then my second vacuum that’s a Roomba and she definitely gives her a run for her money and when it dies I will definitely be replacing her with a Euphy.
