200 Watt Hi-Fi Amplifier

Based on a tried, tested and reliable design using 2N3055 transistors. Relay soft start delay circuitry and current limiting for loudspeaker protection. Easy bias adjustment with the help of two LEDs. This module consists of two separate class AB amplifiers that can provide a STEREO output of up to 100 Watts RMS @ 4 Ohms (70W @ 8 Ohms) per channel. By simply adding a jumper to the board you can turn it into a MONO output of of up to 200W @ 4 Ohms (140W @ 8 Ohms). Includes all board mounted components, large heat sink and kit version has solder for assembly.
