On my Hickok TV-7 tester they read 50/50 and 50/51. A reading of 25 would represent the minimum recommended value. These new-old-stock Raytheon tubes are from 1970’s USA production. They feature black plates, two black grid pin radiator clips at the top and halo getters. The 6BL7 is a medium-mu twin triode. It was originally designed as a vertical deflection amplifier and oscillator for video applications but has recently been finding applications in custom audio equipment. Single plate dissipation is 10 watts.
