I have had the Fosi BT20 for some years now. For some reason the power supply went bad so I have bought another one from a third party on Ebay. Unfortunately, that one did not last very long and therefore I contacted Fosi for the help. Although the audio amp is long time out of the warranty, I was offered a new power supply for very reasonable cost which was supplied some days later. This time I made sure that all possible unnecessary power draw was removed (local volume control) and I hope the present power supply is going to last. Kudos to Fosi!
