Motorola Amplifier Circuit (HiFi)

motorola amplifier circuit

This motorola amplifier circuit has a Hi-Fi quality was excellent. This amplifier circuit can generate a maximum power of 80 Watts RMS at 8 ohm loudspeaker load. Basically amplifier is reinforced with an Op-Amp which is then fed to the end stage amplifier.

Transistors T3 and T4 uses MJ3001 and MJ2501 as the main amplifier. Potentiometer R13 must be set so that the DC current that the minimum voltage at the output, even close to 0 volts.

Fuse F1 on the speakers will be useful when there is damage to the circuit resulting DC voltage entered on the speakers. Resistor R1 and capacitor C1 is a feedback circuit to adjust the gain of the preamp MC1741.
