5.0 6J5 Tube Black With Bass Ajustment

Description:1. Using original 6J5 tube, original NE55322. The main filter capacitor uses the original 470UF/25V, and the coupling capacitor uses the imported capacitor 1UF.3. The resistor uses high-precision chip resistor to ensure a good signal-to-noise ratio of the whole machine.4. PCB adopts 1.6mm thick double-sided sheet, 2.0 oz copper thickness, and tin-spraying process to ensure good passing performance and small currents. First-class PCB quality.5. The input and output are made of gold-plated RCA lotus seat, which is durable and beautiful!6. The board layout is reasonable, beautiful, and the current is small.Specification:Power supply: DC12V 1A-2A ( needs to be regulated by 12V, not 12V)Machine size: about 129* 100* 35MM (without tube height)Panel function: switch treble adjustment bass adjustment lt;/p>Bluetooth : 5.0Package Includes:1x 6J5 Tube lt;/p>Note:1. This finished machine is a , amplifier. It should be used with a post-amplifier active speaker. It is to directly connect passive speakers, speakers and earphones to the power amplifier; if it is not used, the be burnt if the voltage is unstable. It doesn't support phonograph connection, it ;#39; to the phonograph and may also damage our products.2. The probability that the normal supply is not to cause the noise bottom noise is very high. It is recommended good audio cable supply.
