Tips:
?
1. This finished machine is a pre-amplifier, not a power amplifier, it should be used with a post-amp or active speaker. Do not directly connect to passive speakers, speakers, or earphones as power amplifiers; they cannot be used in vehicles, as the vehicle voltage will be unstable and will burn.
2. Poor filtering of the general audio cable or power supply has a very high probability of causing the bottom noise current sound. It is recommended to use a good audio cable or power supply.
3. Make sure that there is no problem with your sound source. The preamplifier itself has a preamplifier function. If the sound source is noisy, the preamplifier will only amplify the noise. Please use a good sound source to test.
4. Check whether the electron tube is properly inserted into the base. Please insert the electron tube into the base. Be sure to insert the electron tube properly when the power is off.
