[QUOTE="Bryant11, post: 8784708, member: 684498"] I am having huge difficulty with op amp circuit used in TA7642 radios, I cannot figure out how to attach the [URL='https://www.apogeeweb.net/circuitry/lm301-op-amp-datasheet-pinout-circuit.html']lm301[/URL] chip to have a gain of more than 200 (10 u cap between pin 1 and if I give it too much signal in 50 k ohm pot then the radio just makes a farting noise. My problem is that I need to figure out which lowpass or highpass filtrations between the speaker pin 5 and the 470 n capacitor and which resistors I need to reduce the hissing noises without any distortion or clipping when I try to make it louder.
