Power Supplys Attempt (2)

[Tom Cloud]

You know, Fred .... Here's the answer (dumb me).
If you're gonna make a switcher, you're gonna wind
a xfmr, right?  Then why not just make a different
one for the PC PS so it runs off 12 instead of 160??
Gotta confess I haven't really thought that out, but
it sure seems feasible right now.  Do you know anything
about winding toroids or pot cores ... and where to
get them?  Now, if you do what I suggest you'll probably
also have to replace the switching xstors with higher
current (but lower voltage) versions -- not a big deal.
