Above scheme is the circuit diagram of 350 studio amplifier uses 4 pairs of transistor MJL21193 and MJL21194 as the main components for this circuit. This circuit requires symmetrical power supply to work.
The scheme and PCB layout provided here is for single channel (mono) application, build two similar circuit for stereo application.

Nice site I like 800watts amplifier circuits but the circuits not clear and no pcb pls sent to me pls sir
Having built the studio 350w amplifier back in 2010 plus adding a few mods to the circuit.
It sounds great with plenty of clean power and work’s on a wide range of voltages
1000w tested and it’s working well if you buy new components
