Datasheet in English: bms.isjtr.ro/sheets/113/6/6N1PEV.pdf

TUBES tested with L3-3 tester
All tubes are new (NOS)

MATCHING QUALITY "1": "THE BEST" tubes - the difference between their parameters is not more than 1%. 

IMPORTANT NOTICE!! 
You can get differ tubes with other parameters,  not like at the photo. 
Because I have many tubes and can not make photo of each. 
So, you will get one Matched PAIR with very similar parameters (WITH 1% tolerance), 
but they must not be the same as at the photo. 

TESTING PROCESS INFO
We actually test all sold tubes on L3-3 testers (sometimes L1-3).
We have more than 10 such devices each ajusted precisely for the specific tasks.
When selecting tubes close in parameter, we re-test on the best (carefully calibrated devices.
It is theoretically impossible to select tubes with a difference of 0% on any device.
From a batch of 100 pieces of any new or vintage number of pairs with a spread of 1-2%, no more than 10.
During testing, any tube changes its parameters by 1-2% in any direction over time.
This information is based on inspections of over 100,000 tubes over many years.
