I have a Squeezebox Touch and use an ELPAC power supply with the Bolder mods. Recently I've started hearing a buzzing sound from withing the power supply itself. I sent an email to Bolder Cable and received the following response:
Can someone translate that into English for me? Can I still safely use this power supply, or should I toss it and start looking for another one?If you are hearing a buzzing sound, it is most likely the laminations on the transformer have dried out. There is nothing that can be done, at this point. The ELPAC WM-220 is not made any longer and there are no parts available for it.
