Provides very fast attack time with no AGC pop. Diodesare 1N914. When voltage across R10-08 decays below that across R9-C7, 03 conducts and clamps AGO bus to ground.AGO threshold is determined by value of RT, between 100K and 470K. AGC line must have high impedance, as with FET IF system. With l0 or bipolar IF amplifier, use low-impedance driver.T1 is audio transformer with 10K primary and 2K secondary (Radio Shack 273-1378).-D. Ste-vens, Solid-State Hang AGC, QST, July 1975, p 44.
