Excellent sounding vintage Pair NOS/New Vintage RCA JAN CRC 5692 Red Base preamp driver tubes, Military Specification, New Balanced test results on my B&K Mutual Conductance tube tester. Both sides of both tubes test over 930(New), where 640 is minimum good. These are considered the very best by many audiophiles and musicians, for excellent sound quality, quiet operation, naturalness and musicality.  They have the incomparable vintage quality, design, craftsmanship, attention to detail, sound quality and performance that only vintage Military Spec JAN CRC RCA tubes can produce. Vintage RCA tubes were used by vintage tube amp manufacturers as original equipment tubes, Fender, Sunn, Dynaco, Scott, Fisher, Gibson, Valco, Vox, etc.  Vintage tubes simply sound better, are made better and last longer than anything manufactured currently. The shipping cost includes safe packing, insurance, prompt shipping and tracking number. Buy with confidence, see my feedback. Good listening, SonnY :)
