Pr Vintage Sylvania 6V6GT Power Tubes, Dark Glass, 1950s, Ex Sound, Sweet, Musical, USA, Test Strong

Pr Vintage Sylvania 6V6 GT power tubes, 1950s, long black plates, dark glass/chrome bottoms, test very strong and balanced on both tubes, incomparable vintage USA design, craftsmanship, attention to detail, performance and sound quality. These vintage 1950s 6V6 tubes just sound sweeter and more transparent than anything made today. They both test over 920(as new) on my B&K Mutual Conductance tube tester, where 640 is minimum good. Vintage USA/European tubes are superior to anything that is made today, they sound better, are made better, and last longer. These were used as original equipment tubes by many vintage tube amp manufacturers. The shipping cost includes safe packing, insurance, prompt shipping and tracking number. Buy with confidence, see my feedback. Good listening, SonnY :)
