On my Hickok TV-7 tester the triode sections read 64 and 65. A reading of 19 would represent the minimum recommended value for the triode sections. The twin-diode sections also test very good. These new-old-stock Sylvania tubes are from the same 1966 USA military production. The 6SQ7 is a twin diode / high-mu triode with octal basing. It is used as a detector, amplifier and AVC tube in many types of AM and Shortwave radio receivers.
