Description: 1. Using original 6J1 tube 2. The main filter capacitor is imported from 470UF/25V, and the coupling capacitor is imported UF capacitor 1UF. 3. The resistor uses a five- 1% metal resistor and a high-precision chip 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 large and small currents. 5. The input and output are gold-plated RCA, which is very durable. 6.

It is not allowed to directly connect passive speakers, speakers, headphones as a power amplifier; can not be used. Second, the use of general audio cable or power supply filtering may cause bottom noise current, it is recommended to use a good audio cable or power supply. Third, please make sure that there is no problem with your own sound source. The preamplifier itself has a preamplifier function. If the sound source itself has noise, then the preamplifier will only amplify its noise. Please use a good sound source for testing. Fourth, check whether the tube is plugged in with the base. Please insert the tube and the base well. Be sure to insert the tube in case of power failure.
