Class A JP-200 Semi-Finished Preamplifier Board With Tube & Tube Socket
Features
1.JP200 is a main amplifier circuit composed of 12AX7 two-stage common cathode class A and one-stage direct-coupled cathode follower. At the same time, in order to make the circuit more dynamic, better resist overload and make the circuit more stable, the output and input stage current Negative feedback is introduced in the feedback section, so the double negative feedback can make the distortion very low. The previous amplifier has a very high index and an excellent sense of hearing.
2.The printed board design strives to be reasonable and symmetrical, and the two-channel symmetrical layout is completely independent. In order to minimize the interference noise, the main amplifier and the power supply of the PCB are on the same circuit board, which reduces the interference caused by the connection line. This makes DIY easier, you only need to connect the power supply/input/output to enjoy the wonderful music! !
3.This is the Jadis JP-200 tube preamp with the most balanced sound and the most musical appeal.
