Class-D Sure-Electronics Amplifier (Inside)

This is my first DIY Class-D amplifier. The amp is based on a $30 Sure-electronics module. The amplifier modules requires only a 30VDC high current power supply because into 4 ohm it can produce 100Wpc. The enclosure is an off the shelf 2U 19” rack mount type. The power supply has an 18-0-18V, 9A toroidal transformer. A 10A rec bridge, some snubbing caps and 30,000 uF of stage caps make up the power supply. Two selectable inputs provide direct connection to the amp module or connection via an Alp pot and 4 Oz brass knob. Very crisp sounding with good detail... See the forum thread Class D 100W power amp for more information.
