    350 Watt Studio Amplifier Circuit MJL21193 MJL21194

    Quite strong quality studio symmetrical amplifier circuit supply voltage + – 2×70 total of 140 volts dc volts DC Volts high voltage, be careful.

    Of the amplifier to the power supply 500 Watt 2 × 50-volt transformer see your work output transistors for the 4 × 4 MJL21194 and MJL21193 used prices can be high, but for this work have been produced quite powerful transistors also this power amp for your circuit output protection circuit would recommend The circuit will have to do . Circuit 8-ohm speakers with 4-ohm speakers with 200w 350w is powering.
