GENERAL OPERATING INFORMATION
The input amplifiers (Q1 and Q2) operate at constant
emitter currents so that input impedance remains
independent of AGC action. Input signals may be applied
single–ended or differentially (for ac) with identical results.
Terminals 4 and 6 may be driven from a transformer, but a dc
path from either terminal to ground is not permitted.

AGC
Input 70

AGC action occurs as a result of an increasing voltage on
the base of Q4 and Q5 causing these transistors to conduct
more heavily thereby shunting signal current from the
interstage amplifiers Q3 and Q6. The output amplifiers are
supplied from an active current source to maintain constant
quiescent bias thereby holding output admittance nearly
constant. Collector voltage for the output amplifier must be
supplied through a center–tapped tuning coil to Pins 1 and 8.
The 12 V supply (V+) at Pin 2 may be used for this purpose,
but output admittance remains more nearly constant if a
separate 15 V supply (V+ +) is used, because the base
voltage on the output amplifier varies with AGC bias.
