A pair of new, old stock SYLVANIA 6CA4/EZ81 rectifier tubes, in original boxes. These are reliable and well constructed. The 6CA4/EZ81 is still a popular tube. Why take a chance on a new JJ or Chinese brand when you can still obtain US made NOS for about the same price?
These tubes were tested on calibrated Hickok 6000 tester, with identical strong readings for emissions. All other tests were strong for life, filament continuity and were also negative for gas and shorts. Stock up now. You know you want these. Just $39.95 for the pair, shipped to a U.S. address.
