I have few 100pcs boxes of these EL84, they are made for East German army and for export in 70s, without printed logo, these tubes passed strict quality control and they are the best examples from the same batch!
They are carefully matched by plate current and transconductance on my Metrix and Hickok testers from a big batch of the same code tubes.
The tubes are shipped in generic white boxes.
I collect tubes and tube gear for more than 35 years and I start to sell recently, please be sure to check my other items and visit my store for more rare NOS tubes and parts.
