[Boatanchors] 51J4 Muting 12v PS?

[Glen Zook]

Most of the units have VERY bad voltage regulation. 
The voltage drops when even a moderate load is
applied.

Seems I have a bunch of these wallwarts that are
labeled for 12VDC output. I noticed that some output
12VDC such as an old laptop wallwart. However, some
others that are labeled as 12VDC actually output
something like 20VDC when I measure it with my dmm.
One example is a wallwart for a cordless phone. It is
very small and the output says 12vdc 200ma.  It
measures 20vdc on the dmm.  Why would this be? I get
the same result on a couple of these wallwarts, so I
don't think its a fluke.
