     The Radio Shack 273-1653 supply (12v, 1a) produces about .2v of
ripple when delivering 250ma into a resistive load.  This increases to
.3v at 500ma.  The output voltage also drops.  

     I had just assumed that these little supplies had 7812s in them.
No.  Fortunately, Stancor has some real wall-transformer type power supplies.
