Only down side is that Hosfelt hoses you on the shipping and handling. The power supply was $7, plus a $5 handling fee, plus $15 freight (almost *double* the actual postage of ~$8), totalling $27. Probably still worth it though. So a few other observations with the Hosfelt: You definitely notice, as a linear power supply, it is not as efficient; the case stays nice and warm. It has a noticeable 60 Hz hum from that transformer; I can hear it quite distinctly up close and, when the room is otherwise silent, from about 6 feet away. -- Daryle A.

You could also do the job by snipping the end off an old AC adapter with the same end that you might have hanging around and then soldering the two wires together. That's what I did. Between home and work I have over a dozen from defunct electronics. They always come in handy! positive tip/center right? Right. But always take your DMM and check twice with the original and solder once. Then check again before plugging into the SB. -- Daryle A.

It's about $10 less expensive than the elpac and looks like a much better design. I plugged this supply in during the AM radio test and didn't notice any problem. I've not tried this supply with the Squeezebox yet because the connector needs to be replaced. That's the nice thing about the elpac, it's plug'n play. Well I just ordered the Hosfelt 56-534 mentioned in that thread as well. It looks like a nice heavy duty linear PS from the pics plus it's not a wall wart. We will see in a few weeks if it does the trick. Well I hooked up the Hosfelt supply; and what a difference. On the AM dial all power supply interference is basically gone.
