Hello Marc:

You have brought out a good point.  The Powerstat T5587 choke is nothing
more than a small toroidal core.  It is about a 5 " O.D., 3 1/2" I. D. and
about 1" thick.   There are two separate windings on it.  These are made
with what appears to be about #8 wire.  This is from memory from last
September.  Here in Wisconsin it's a bit too cold to poke around with
coiling in the winter out on the drive way. I simply haven't rolled the
power cabinet out of it's corner yet this year.
It's probably $25.00 worth of electrical parts -- real nice $122 bakelite
case, I guess! :^)

I would not buy another one of these.  I did already see Scott's comments
about making your own, and I think he has made some good observations.  Just
make sure to get the turns direction correctly wound.

Chuck
