1. Using 6J5 tube, NE5532
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 of large 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! The board layout is reasonable, beautiful, and the current is small.
Basic parameters:
Power supply: DC12V2A ( needs to be regulated by 12V, not higher than 12V)
Machine size: about 129* 100* 35MM (without tube height)
Panel function: switch treble adjustment bass adjustment total volume
Note:
1. This finished machine is a preamplifier, not an 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.
3. Make sure that there is no problem with your source. The preamplifier itself has a preamplifier function. If the source itself is noisy, then the preamplifier will only amplify its noise. Please use a good source test.
Note:
Power supply is not included in the package. You need to buy 12V2A power supply by yourself.
