A cap reactive supply can be good. A 1uF poly cap
    is about 3200ohms at 50Hz and 2700ohms at 60Hz if
    I remember properly. Xc = 1/ 2pi f c

And it has to dissipate as much power as a 2700ohm resistor, right?
A bit of a problem, since caps are rarely rated for power dissipation.


    Capacitor quality is everything, I prefer the 630v
    polyester caps, these are great especially if you can
    get the blue "milspec" ones.

Isn't a 630V 1uF "milspec" poly cap somewhat ... large?  Say, close to
transformer sized?

Actually, a shaver I took apart recently looked like it had a particularly
interesting circuit involving a resistor in series with the primary of a
very small transformer.  (It didn't actually have this, but it sorta looked
like that originally.)  Can you do this in reality - limit the primary
current to allow a smaller transformer?
