I'm sure that textbooks give informed readers the basic theory but not all of us on this list are competent to use it. Besides, the difference between a textbook circuit that works and a practical one that works well needs theory informed by experience and an eye for detail.
I do not understand why folk feel the need to be ungracious about a useful contribution to the list. If they think the design lacks merit, they should of course say why but it is wrong to suggest that John has merely rehashed a design note.
I've looked at dozens of power supply designs over the years, many of them very good. I've seen several broadly similar to John's (as you'd expect) but none identical and certainly not in the data sheets or in this context.
I find his argument about its merits convincing and it looks easy to build. It seeks to address a significant issue with PC audio and adds support to the notion of "satellite" players that he has been plugging.
I'd like to pursue the idea of adapting cMP2 to use such a device as (a) I don't know Linux but am reluctant to make the effort to learn it right now only to find I can't get it to work with my kit and (b) I am very satisifed with cMP2 and would need some convincing that Linux alternatives are better. (Never say never and all that but also a step at a time.)
Nevertheless, the core argument for using the likes of Fit-PC is strong and John's proffered PSU design adds to it. Many thanks for the effort.
