AJMRTC Mono 200W Power Amplifier Board, DC 20V90V 1943+5200 Power Tube Finished Mono Audio Amplifier Module, HighPower SingleChannel Amplifier Board for DIY Speaker Audio System Modification

AJMRTC 200W mono finished power amplifier board uses classic 1943+5200 power tubes as core output components to provide highpower singlechannel audio amplification. Working with DC 20V90V wide input voltage, this completed amplifier module can be matched with different DC power sources to drive medium and highpower speakers. Optimized analog circuit design effectively lowers audio distortion, outputs stable and natural sound performance, which meets the demands of DIY speaker assembly, audio cabinet modification and home audio system upgrade. This is a presoldered finished board, users can complete wiring connection directly without complex welding work. Basic protective circuits are integrated on the board to mitigate damage caused by shortcircuit and abnormal current. It is wellsuited for audio hobbyists, DIY audio makers and smallscale audio equipment renovation. Adequate heat dissipation measures must be arranged during highpower continuous operation to prevent overheating damage to power tubes. Please match speaker impedance and power parameters reasonably when using.
