Originally this 1U rack mount enclosure was intended for another chip amp which really didn't work well. Now with a LM4780 cct. brd. and repurposed this low profile amp really sings. Currently being used around the TV system and controlled by a single stage tube preamp. Lots of power (60W) into high efficiency single driver Mark Audio speakers and backed with a 175W sub-woofer. Pleased wih the outcome and the repurposing of the chassis and robust PS. Under test in the second image.
