Toroid xfmrs

[d3imlay]

I need a 200 VA or greater toroid with a secondary around 125VAC. Who sell them? Tried Parts Express and plitron but not quite what I'm looking for.

I wiould think that a surplus isolation amp might work well, since you don't seem to need to change the voltage- assuming that you have 120v at the wall...
