Offered is a pair of NOS new old stock GE General Electric mil spec type JAN 5751 dual triode tubes, with ribbed plates. Made in U.S.A. dates codes of 67-48, and 78-48 which I imagine is 48th week of 1967 & 1978 The 1967 vintage tube is a 5 star tube with 5 stars in a row on it. I tested these on my restored and calibrated Hickok 539B tube tester, that was gone over by Chris Haedt, who was a tube tester expert, who has since passed away. I am confident in my tester's reading. The minimum acceptable reading is 875 micromhos, was that is the point w the tube is considered to be starting to become weaker. These tested as follows: 1400 & 1350 uM 1967 tube1800 & 1700 uM 1978 tubeWill combine shipping if you win any of the other tube lots...Sold as is, due to unknown user applications.
