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. Figure 4.

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.
