Class-T Amplifier Known as AMP6

The construction of the Class-T amplifier project is offering both the audio fidelity of Class AB and the power efficiency of Class D amplifiers.

The Tripath TA2000 chip is being used by the small amplifier AMP6 which includes an onboard regulated power supply. During the construction, a multimeter is used to determine the polarity marking on the diodes. The regulator is isolated from the heatsink while the amplifier does not need to be isolated. The heatsink was salvaged from a dead computer power supply which also provided the IEC socket, power switch, and fuse holder along with the transformer being salvaged from a dead computer UPS.

In order to have room to fasten the regulator to the chassis, the tank capacitor had to be moved to the underside of the PCB. For DC blocking on the input, electrolytic capacitors that comes from the kit are used while the volume control is a 100K Alps Blue Velvet. The input is via the inexpensive gold plated RCA jacks with inexpensive gold plated binding posts used for the output.

To allow switching between ON and sleep/standby mode, a small toggle switch is placed on the front.
