Simple unregulated switchable dual voltage rectifier circuit

Hi Guys,

Ages ago I saw a very simple circuit - a CT transformer, couple of
caps, 4 rectifiers and a change over switch.

With the switch in one position, the circuit was a bridge rectifier,
in the other, a voltage doubler.

Pointers please, I have forgotten where I saw this...

Thanks,

Mark
