    Up for sale 2 quartets (total 8 tubes) Εi ΚΤ90 Yugoslavia, scarce, originals, matched, selected from Jadis.. Not many hours of use, measured in a calibrated tube-tester with (gm=100%) and measurements written on the tubes bases.. All tubes were backup in 2 Jadis Power Amps that were working mainly with Electro- Harmonix..

    Εi ΚΤ90 Yugoslavia are hard to be found, they give the best sound in amplifiers using EL34, ΚΤ88, 6550, by directly swapping all above tubes, Jadis selected.. In few of those tubes the delicate lettering has been erased partially oe even completely, please look at the photos.. will be posted in EH boxes.. price 400€ for one quartet(4 matched tubes), 800€ for two quartets (all 8 tubes)..
    please send pm.. Thanks.. Manos
