As you predicted the bridge would output a full-wave rectified ac.
That has a large
dc-component. Feed that in to a neon primary and you'll see the core
saturate in
no time becouse it is not supposed to handle large dc! The approach
will just not
work. Try it out to see for yourself, low-current bridges are not
that costly to be
popped up for nice effects :) :)
