  1. Thanks Koray, All tubes arrived very safely. They are exellent condition and already deliver good sound even before maturing.
    Thanks again. I will back soon to place order for more tubes.

  2. Just received my Mullard GZ34 (7 Notch). Very well stored & protected stock! It doesn't get any more NOS than this!!! Thank you very much for your excellent testing, labeling, packaging & prompt shipment. You're the best. Hope I can get all my tube needs before too many people discover you!!! All the best & THANKS!!!

  4. (Mullard GZ34 Rectifier) Such a nice, quiet, yet strong rectifier. Much better than the Sovtek crap that came with the amplifier.

    Thanks Koray!

  5. Can a GZ34 make that much of a difference in a stereo amp? I guess I have to say yes! After a few weeks of having the tube installed, my stereo started to sing again. The bottom end came back, the sound stage widened and the upper range was clear without harshness. I can now hear my Harry James direct-to-disk albums, with his horn wailing, without any distortion. I'm just about to order a total tube replacement for my pre-amp -- 8 tubes. Koray is the greatest!

  6. Excellent valves, well packed and speedily sent out. Have performed faultlessly and made a huge difference to the sound!! Thank you Koray

  7. Very good tube. Made a visible difference on the Audio Research Ref One phono stage. Warm but also resolute. Very efficient service. Highly recommended.
