Hi fellas! While not completely convinced about the benefits of a linear power supply for the Squeezebox, the idea of building a dedicated supply seemed like the perfect weekend project.
I headed to Gateway Electronics, one of the few decent places for surplus electronics here in San Diego. Overwhelmed by the wide variety of chassis power supplies, I was about to settle for a 5 volt 1.5 amp Atari walwart probably intended for a 1980's computer. It was heavy enough but the case appeared to have been welded shut, no screws. That was a big no-no, so I headed back to the power supply section. After looking at a few oddly shaped and old Lambda supplies, I came across a nice linear chassis with a fairly hefty transformer and plenty of TO220 regulators. I noticed it was made by Elpac and it was rated at 5 volts 2 amps, presto!!! looked like the perfect supply for my project. The open chassis was not suitable for safe operation without some sort of case. I found a nice aluminum project case that would prove a perfect fit. To round up the supply I bought a fused IEC connector, power cord, fuses and two color coded binding posts. Total cost was around $40. Here's a shot of the naked chassis while doing initial power-up checks. Voltage was a rock steady 4.99 volts on my Fluke VOM. +-------------------------------------------------------------------+ |Filename: supply1.jpg | |Download: http://forums.slimdevices.com/attachment.php?attachmentid=947| +-------------------------------------------------------------------+ -- crooner Squeezebox 3 Lite Audio DAC60 tube DAC Pioneer SX-1980 Vandersteen 2Ce Signature Vandersteen 2W ------------------------------------------------------------------------ crooner's Profile: http://forums.slimdevices.com/member.php?userid=3379 View this thread: http://forums.slimdevices.com/showthread.php?t=21505 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/audiophiles
