Our users rate Reverb
Rare vintage JAN Military Spec 1950s Sylvania CHS-5931(5U4/GB) rectifier tube, triple mica, D Getter, black plate construction, brown phenolic base, hefty incomparable vintage USA design, craftsmanship, attention to detail, parts quality, and performance. It tests very very strong and balanced on my B&K Mutual Conductance tube tester. Both sides test over 920, where 640 is minimum good. The shipping cost includes safe packing, insurance, prompt shipping and tracking number. Buy with confidence, see my feedback. Good listening, SonnY
PS: Vintage USA Military Spec tubes are simple superior to anything that is manufactured today
