Here the great 35W power amplifier with single IC STK-082 from Sanyo Semiconductor. Simple circuit with high power output.. 🙂
This circuit uses symmetrical (dual polarity) power supply with maximum power voltage is 43V based on the datasheet document. The recommended voltage operation is +/- 30V. For stereo application, you just need to build two similar circuit. Use minimum 2A center tap transformer for stereo channel amplifier.
Use this kind of dual polarity power supply circuit:
- @lMST, l Channel? by 2 Power Supplies
- Differential amp. constantc current driving.
- Capable of tone controlling.
