Hi-Fi Amplifier Circuit
Working & Description:
- Circuit delivers 12 Watts power on 8 Ohm speaker for each channel at +/- 12 V dual supply.
- K1 & K2 are speakers on pins 4 & 6
- 3 and 8 are grounded
- 1 and 9 are left and right inputs
- 5 and 7 are provided voltages
- Circuits consist of capacitors and resistors combination.
Tips for better results:
- Use ceramic capacitors.
- Capacitors must be rated 50V.
- Use a well-regulated and filtered +/- 12 V dual power supply that is able to provide at least 2 A continuous current.
- Use PCB of good quality
