3. The resistor uses a five-ring 1% metal resistor to ensure a good signal-to-noise ratio.
4. The PCB adopts 1.6mm thick double-sided sheet, 2.0 oz copper thickness, and the whole process of tin-spraying ensures the good passing performance of the current. First-class PCB quality.
5. The output is made of gold-plated RCA lotus seat, which is durable and beautiful!

Note:
1. The product is a preamplifier, not a power amplifier. It should be used with a post-amplifier or an active speaker. It is not allowed to directly connect passive speakers, speakers and earphones to the power amplifier; if it is not used, the car will be burnt if the voltage is unstable.
2, The general audio line or power supply filtering is not good, the probability of the bottom noise current is very large, it is recommended to use a good audio cable or power supply.
3. Make sure that there is no problem with your own audio source. The preamplifier has its own preamplifier function. If the audio source itself has noise, then the preamplifier will only amplify its noise. Please use a good sound source test.
4. Check if the tube is plugged into the base. Please insert the tube and the base. Be sure to insert the tube in case of power failure.
