120W rms power amp OCL Transistor bipolar

A friend takes an interest to want to try build hi-fi power Amplifier the some one. He likes model class AB , because the sound is good. keen bass good distinct.I chooses this circuit gives him sees , be power Amplifier hi-fi OCL 120W rms sizes really,if use power supply circuit at enough good and use 8ohm size prominent point interesting loudspeakers. Of the circuit be use the transistor entirely have no the integrated circuit mixes. Then make bland good sound , for power supply voltage should use +40V GND -40V sizes give current about 4A. Other detail please see in circuit picture better.

80 Watt IC LM3875 Audio Amplifier

This Audio power Amplificator will deliver 80 watt of audio into an 8 Ohm load. The LM3875 IC devices should be suitably heatsinked. Note that the amplifier is a bridged circuit, with both speaker leads “hot”.

Note:
You should use supply Voltage about +/- 25Volt at do not lower 2-3A.

60 Watt Power Amplifier by TDA1514A

This one is already pretty strong. It’s got a handful of additional external devices in comparison to the generic schematic. Note that there’s a simple HF filter on the input. This IC supports mute and stand-by modes. I’ve never built this one, so I’ve got no suggestions concerning practical construction.
