Dear friends,

I need to get low hum design so please hlep me are there any mistakes in the pcb.

I need to drive a load which needs about 4 amps of max current at the output.

I think the pcb is sufficient.

here are my warnings:
1.) no input
2.) no input GND
3.) no +Vcc
4.) no Output.
5.) Capacitors C1, C4 appear to extend beyond the edge of PCB. Do you have a geometrically correct heatsink for the IC.
6.) Capacitor C1 is on top of resistor R1
7.) Resistor R1 does not appear to be in the circuit.
8.) Capacitors C1, C4 would block a metal bar if a clamping type mount style is used.
9.) What of the 100nF ceramic capacitors?
10.) Board appears to extend beyond the IC. Do you have an acceptable heatsink?
11.) are pad7, pad8 of sufficient size for power and gnd wires? I reccomend terminal blocks.
