Acting as the "muscle" for the output stage, this section ensures the final power transistors have enough current to switch properly.
A massive power supply is required, often utilizing a heavy-duty transformer (e.g., 1KVA) and a dual DC supply (e.g., ±70Vplus or minus 70 cap V ±90Vplus or minus 90 cap V ) to provide sufficient "headroom". 1000 Watts Power Amplifier Diagram
arranged in parallel to handle the massive current required for such output. Key Stages of a 1000W Amplifier Acting as the "muscle" for the output stage,
