Pair NOS Silvertone 6SN7GTB Tubes, Boxes, Chrome Tops 1960s, Ex Sound, USA 1960s

Pair NOS Vintage Silvertone 6SN7GTB Chrome Top preamp driver tubes, relabeled and made by Sylvania. Silvertone never manufactured tubes, all of their tubes were purchased from other manufacturers and relabeled with their own name. Relabeled was common practice with vintage USA and European tubes. Of course these Sylvania Chrome tops are well known and highly recommended for their sound and performance. These are brand new in the boxes. They have the incomparable vintage USA design, craftsmanship, attention to detail, and performance. They sound superb, open, detailed, dynamic, extended, transparent, smooth, natural and musical. They were tested on my Calibrated B&K Mutual Conductance tube tester. They both test new and matched. The shipping cost includes safe packing, insurance, prompt shipping and tracking number. Buy with confidence, see my feedback. Good listening, SonnY :)
