Resistive colllector network of symmetrical differentrial amplifieris replaced by constant-current source to improve slew rate of deflection amplifier driving capacitive load such as deflection plates of electrostatic cathode-ray tube.Q1 and Q2 are idetical current sources,Network Q1-CR1-Q7-R6-R8 forms current source for Q1, Q7, is used as 6.2-V zener diode,－W Peterson,Current Sources lmprove Amplifier Slew Rate,EEE Magazine, Nov,1970、p102.
