    1. There is a large probability that the low-quality audio cable causes the static noise.
    2. Please make sure the sound source is fine since tube amplifiers will amplify all sound including the noise.
    3. Please check whether the tubes are plugged well on the tube sockets or not.
    4. Devices like routers, mobile phones will also interfere in the audio signal and may cause static noise.
