I am looking for a stunt box that will switch my stereo receiver on
according to whether or not my turntable is running.  This strikes
me as a basic and common need, and while I think I could design a
circuit to do this I can't believe that I can't buy a better one, or
at least get ahold of plans for one.  Basically what I want is
something that will sense when current is drawn through one AC
outlet without significantly degrading the power available, and
control a second outlet according to whether or not power is being
drawn.  I'd also like a control switch allowing the second outlet to
be always on, always off, or switched according to the first.  I've
poked around in a couple of stereo stores but haven't found anything
like this, and as I said while I suspect I could build such a gadget
I suspect I could buy a better one.  Anyone have any suggestions as
to what to look for or ideas for building such a gadget?
