One perfectly matched quad (4 tubes) of genuine EL34 / 6CA7 made by RFT tube factory in Muhlhausen, Germany in 60s.
They are from big service packaging of 100 pieces in original individual boxes. Genuine dimple top, with single O getter. Mica spacers with 10 support points, stapled plates, two holes on plates, black base with engraved code in guiding pin like!
I have few 100 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 RFT EL34 with perfect prints and the same codes today, be fast and take this opportunity while they are still in stock!!!
These tubes were sold under Telefunken, Siemens, Philips and few other brands since late 70s, when West European plants were closed and there were still high demand for these quality EL34 / 6CA7.

Quick install of cartrage and software for printer counter
At first had trouble. The instructions that came with it would not reset my printer. I emailed the seller and about 24 hours later I received another set of instructions that worked on my printer. The price for 4 is great I now have a good supply of back ups. I have and do recommend this. It was an easy install of the ink tray, good quality and fit perfectly. It is compatible with several printers.

Easy process
I only used it once, I don’t know how the other 3 keys are supplied to work because I did not see any counting bit it work perfectly. It was super easy, my only issue is that I had to download the driver and restart the pc to make everything work out but the process itself is pretty easy. The printer work like new and the installation was easy too.

Fits perfectly in the Epson ET-2720 and reset software worked!
The waste ink pad replacement fit perfectly in the Epson ET-2720 and looked to be identical to the original that needed replacing. The reset software they provide also worked without any issue.

Not everything included
It says it comes with program to reset the printer an all the information that came with the tanks takes you to sites that want you to buy the key to unlock. These were purchased with the idea everything you needed came with it.
