Auction is for one platinum matched pair (2 tubes) of rare EL84 6BQ5 EI Yugoslavia made back in 80s. 

They are hi quality EL84 pentodes, made under Philips Mullard licence and on original Philips tooling - early version rectangular plate holes, much better sound than later round hole plates. Gray plates, halo ring, copper grid posts. They can be used in all EL84 / 6BQ5 applications.

They are carefully matched by plate current and transconductance on my Metrix and Hickok testers.

This auction is for matched pair (2 tubes) not for a quad (4 tubes)!!!
