>pix, that's one of the sites I reviewed but it just copies the same scheme
that seems to be all over the net.... a cap from hot to chassis, and neutral
to chassis. But again, that's a capacitative voltage divider, and there's still
a 60VAC tingle.
>magicclocks, the site sighted and cited
by pixellany gives a good rundown
on the types and values of safety caps to use:http://www.justradios.com/X2capacitors.html
>Jonnysan, one of the schematics they show has a cap directly across the line
in, with Y-caps downstream. Again, making a voltage divider.
The transformer powered radio I'm working on right now had no line caps of
any kind on it but I put a couple on... hot to chassis and neutral to chassis. I'm
not enamored with the tiny spark when I hook the ground lead of my scope to it,
but still would like to kill some line noise. The radio has a two wire polarized plug,
and for several reasons I'm reluctant to put a three-wire grounded cord on it.
I'm still mystified as to why the hot-to-neutral and neutral-to-chassis scheme is
not suggested as an option anywhere...
