Sanken C2837 A1186 200W Mono DC +-20-60V Class AB audio amplifier

AB class audio amplifier board with 200W power for 4 ohms and 120W for 8 ohms.

NOTE: requires a symmetrical DC power supply; a standard power supply will not work.

Specification:

• mono power: 200W at 4Ω impedance and 120W for 8ohm
• power supply: symmetrical DC power supply +-20-60V
• amplifier transistors: Sanken C2837 A1186
• Dimensions: 190 x 46 x 25 mm.

The transistors require a heat sink and an insulator between the heat sink and the transistor.
