https://electronics.stackexchange.com/questions/423147/reducing-noise-in-this-audio-amplifier
Top 3 things to try for almost any circuit with a noise problem: 1) Power supply. I'm not going to compute a PSRR for this but for any feedbackless amplifier it's likely to be poor. To... 2) Power rail decoupling. I can't see any. You've got 100u and 0.1u caps handy, put some across the power rails ...

Some op-amps are much more noisy than others. They produce noise and it cannot be eliminated; it is inherent to the op-amp. If you're doing audio work, and the circuitry doesn't have to be very low power, use an audiophile op-amp IC like LM4562 or the …
How to Reduce Noise in Low-Voltage Amplifier Designs ...

For low-gain amplifier configurations, the addition of a low-pass resistor-capacitor (RC) filter at the amplifier’s output can be a more effective method for reducing noise. The idea behind this technique is again to attenuate higher frequency ranges that only contribute noise, while continuing to pass the signal frequency.
Amplifiers: How to Suppress Noise

Kenny, that cooling fan is definitely the source of your noise problem. The fan, being a big electromechanical device, is generating a ton of RF noise into the electrical system. The best thing to do is to get the fan entirely out of the stereo system's electrical circuit. Try the following two things: Change the grounding point for the fan.

pradhan.rachit said: In any system, the SNR (Signal to Noise Ratio) is highest at the input. It keeps on degrading as we go through the stages of the amplifier, and hence some amount of noise is added in every stage. Replacing the 741s with NE5534 will onviously yeild a …
How to reduce noise in an amplifier - Quora
https://www.quora.com/How-do-I-reduce-noise-in-an-amplifier
Answer (1 of 3): The problem is not likely your speakers. When you use the headphone output, you are hearing the output of the preamp in your unit. That sound is then sent to the power amp section and then out through your speakers when you listen through the speakers. Any noise in the preamp is ...

Moving away from the amplifier will help a ton, but the type of pickup matters, too. Humbuckers are designed to reduce the amount of noise transferred to the amplifier by using two coils with opposite polarity (this cancels or bucks the hum). They aren’t perfect but do essentially cancel out any noise that may come through.
