jillmark99 Posted June 20, 2021 Share Posted June 20, 2021 I have 2 Control4 amplifiers in my system and they have worked great for years. Today I woke up to one that is no longer powering on. It emits a slight buzzing noise when plugged in. When I unplug it the buzzing goes away. The buzzing comes from the amp itself, not through the speakers. I have not removed it from the rack yet or done any additional troubleshooting. I’m assuming it’s the internal power supply. The amp is model number AVM-16A2-B. It also has a tag on it that says AVM-16A2-BX. My question is can someone tell me the correct part number for a power supply? I assume one could be purchased on Amazon? What is the difficulty in swapping them? Does it require soldering internally or do they unbolt to swap out. I’ve never opened the case. Im hoping I can simply swap out the power supply easily rather than purchasing a new amp. your help is appreciated. Quote Link to comment Share on other sites More sharing options...
lippavisual Posted June 21, 2021 Share Posted June 21, 2021 If it’s dead, uninstall it, open it up and purchase a like power supply. I doubt it is under warranty. Quote Link to comment Share on other sites More sharing options...
