1.6kg, 100W per channel, Class-T with SMPS.
Just finished this amp that some may find interesting. I wanted to build a 19″ 1RU (rack unit) Class-D power amp that would be light and compact. Using the ConnexElectronic TA2022 amp module, the SMPS250 PSU and the speaker protection module. It was a bit fiddly as I had to cut 5mm off the heatsinks and replace all the big caps with 35mm ones.
