( Pullouts from new equipement!)

ECF80 / 6BL8 EI Nis made in Yugoslavia. Same plate structure like Philips ECF80 mabe by Mullard, Blackburn, pentode ribbed plate one side hole + two side slots, triode smooth plate with two side holes, just getter support is different, in EI tubes it’s double support construction.

I tested just few of these tubes, but they are actually pullouts from new receiver modules sealed in cellophane. Possible very close matching thanks to big number of same tube construction and identical codes.

I also have many used ECF80 by EI Serbia. On this photo you can clearly see the difference between used tubes (like new NOS) and real used tubes!!!
