Amp6 T-Amp: DIY Class-T Kit
Here’s the intro for this interesting project:
“In late 2004 and early 2005, raving reviews about the $30 Sonic Impact T-Amp started to surface. Some called it a “Giant Killer”, some did not like it, but most agreed it was an inexpensive audiophile-grade amplifier. The favorable reviews had me wondering about Class-T amplifiers so I decided to try one on for size. Taking the DIY route, I opted for a $39 AMP6 kit from 41hz.com.
The AMP6 is a small amplifier that uses the Tripath TA2020 chip and includes an onboard regulated power supply. The manufacturer, Tripath Technology, Inc. describes Class-T amplifiers as offering both the audio fidelity of Class-AB and the power efficiency of Class-D amplifiers. “
Sweeeet.

The THD on this is horrible really. 0.03 from 0-2watts. Dives down to .018(?) at almost 7 watts and rockets up to 2 at 10 watts. It would be OK if you wanted to do only 7 watts in 8 ohms. I would stick with the LM-3886 stuff.
