Tips:
1. This finished machine is a preamp, not a power amplifier. It must be used with a post-amplifier or active speaker. It is not allowed to directly connect a passive speaker, a speaker or a headset as a power amplifier; It can’t be used, and the car voltage is unstable. Burn!
2 the general audio cable or the power supply filter is not good enough to cause noise from the bottom current It is recommended to use a good audio cable or power supply.
3. Make sure there is no problem with your own audio source. The preamp has a preamp function. If the audio source itself has noise, the preamp will only amplify its noise. Use a good sound source test.
4. Check if the tube is plugged into the base. Insert the tube and base well. Be sure to insert the tube in case of power failure.
