Not for this application, NO WAY! Fairly inexpensive "non-polar"
electrolytics are used in AC circuits all the time, in speaker crossovers
for example, and motor starting, but there are none that I know of that
would be of any use for NST Power Factor Correction. They just can't handle
the continuous currents that we're dealing with.
You can go ahead and experiment, but be very sure that you are well
protected from the blast of hot alkali that will inevitably spew from the
