2.2-watt AF power amplifiers for low-cost phonographs using an EGG1112 14-pin DIP. The 2.2-watt rating is based on a 16-ohm load. Recommended supply voltage is 18 volts. Input impedance is 150K. Typical voltage gain is 72 dB. Current drain at maximum output is 175 mA. Capacitor OF can be either 510 pF or 820 pF. With OF at 820 pF the frequency response falls off at about 8 kHz; at 510 pF it extends up to 10 kHz (courtesy GTE Sylvania Incorporated).
