I bought two of the (semi-famed) Power One HB5-3 power supplies. I use one for my Squeezebox 3 and was planning to use one for the Duet I had on order.
OOOPPS!! The Duet needs 9 volt in, not 5. Hmmm... Anybody know how to change the HB5-3 to 9 volt? Just a matter of a resistor or two I am guessing, but anybody know which ones? I found the datasheet for the LM723N used in the Power One here: http://www.chipcatalog.com/ST/LM723N.htm The datasheet shows schematics for applications, and I'm guessing the schematic that applies to the HB5-3 is either schematic #16 or #17, but that's as far as my limited electronic neurons take me... -- atkinsonrr Transporter, Quicksilver V4 Monos, Vandersteen Model 5A speakers.
