Pr GE 7199 Preamp Tubes, USA Test Strong/Balanced, Quiet, 1970s, Ex Sound

Pr of  GE 7199 Preamp Driver tubes, test strong and balanced on my B&K Mutual Conductance tube tester..They were quality designed and manufactured in the USA,1970s. Both tubes on both sides test over 900 on my B&K Mutual Conductance tube tester, where 640 is minimum good.  Vintage GE tubes were used as original equipment tubes by many vintage tube amplifier companies.  They are quiet and sound very nice. Vintage tubes simply sound better, are made better, use better materials, last longer and sound better.  The shipping cost includes fast shipping, insurance and tracking number. Buy with confidence, see my feedback. Good listening, SonnY :)
