RCA IC includes preamps, power amplifier, and integral heatsink. CA3131 has internal feedback network that maintains 48-dB gain, while CA3132 requires external feedback network including R1 and R2 connected between pins 6 and 16. Input 1000-pF capacitor is required if input has open circuit. Electrolytic C1 should be placed as close as possible to pin 10，C6 sets 46-dB closed-loop gain pointat 200 kHz C7 equalizes gain for positive and negative signal swings C9 sets low-frequecy response of amplifier Recommended suppiv voltageis 24VDC，-E.Noll, Audio-Power Integrated Circults,Ham Radio、Jan 1976、p 64-66
