#2 Amphion Impact 500 (DB Series DB5004) subwoofer amplifier autopsy (and repair, hopefully)


Right, so i've had this amplifier brought in last week (sans the subwoofer enclosure itself). When i noticed the brand, i remarked to the owner that, to the best of my knowledge, Amphion stuff is anything BUT cheap. He confirmed, this whole thing having costed him something over a grand(!!!), a couple years ago.


It had allegedly been serviced before, and he pointed at an electrolytic cap. A ChemiCon SXE - totally out of place on a board otherwise full of CapXons. Yep... Oh joy...
