New in original boxes, gold pins, diamond bottom!
These tubes were made in 60s when gold pins really meant quality. Today a lot of cheap tubes are gold pins and they are sold like premium versions – now it’s just marketing ploy. These are super-premium version of 6922 tube, with guaranteed matching between the two triodes and also, other characteristics are specially tested for and controlled. Very dimensional and musical tube, with smooth, balanced and realistic highs. Lots of air and depth, great imaging!!! Geniuine Telefunken tube with diamond bottom <>. The best E88CC 6DJ8 6922 ECC88 I’ve ever tried.
Diamond bottoms <>, gold pins, original boxes!

Hello Dragan and thanks for your recommendation. These Tele’s sound fantastic in my AUDION PREMIER QUATTRO LINE Q4. I have tried 6N23 and few different current production 6DJ8 / 6922, but now I can understand all the fame about Telefunken diamond bottoms!!!
