4-watt AF power amplifiers for low-cost record players using an ECG1111 14-pin DIP. The amplifier is designed to drive a 16-ohm load. Recommended supply voltage is 24 volts. Typical voltage gain is 74 dB. Input impedance is 110K, Capacitor CF can be either 510 pF or 820 pF, depending on the frequency response desired. For 510 pF the frequency response extends beyond 10 kHz. With CF at 820 pF the response falls off at about 8 kHz (courtesy GTE Sylvania Incorporated).
