Auction is for one matched pair (two tubes) ECF802 6JW8 made by EI Yugoslavia under Philips liscence in 80s.

These are fine EU NOS tubes made in EI NIS tube factory back in 1986 on Philips tooling machinery with quality control by Philips engineers.  They are copper grid posts version, without printing, they have been made for export and they can be found relabeled Siemens, Philips, Valvo, AEG and Telefunken.

They are perfect replacement for McIntosh equipment MR67 MX110

I have few hundreds of these tubes and I had enough time to match them carefully, so you'll get platinum matched pairs within 5% or less.
