I make this when I though I was going to make a tri-amp system with horn mid-range and tweeters. It is two DTA-2 Class-T amplifier modules from Parts-Express with a packaged power supply. The DTA-2 modules are modified so you can set a pot and zero the DC offset. I though zero dc offset was needed if the amps were to directly drive horns. I hooked up and tested on of the modules into a dummy load and it worked fine. Pictures below -
