The wiring is very simple, especially for beginner DIY. With cooling fan, good heat dissipation performance.
The circuit uses a total of 6 disassembled power amplifier tubes and 2 disassembled large capacitors, 4 of which are responsible for the left and right channels, and the other 2 are connected to the BTL circuit for subwoofer use.
Working voltage: AC dual 18-24V (recommended dual 24V). Maximum output power: left and right channels 100Wx2 subwoofer 120Wx1. Output impedance: 4-16 ohms
Made of high quality electronic components, stable and reliable performance.The whole circuit board is designed reasonably and with low noise.
The potentiometers from left to right are the subwoofer volume, treble adjustment, and the total volume of the left and right channels.
