Yeah. That's the one: the Dutch underground used that same design in a PS 
they used with a "spy transmitter" during WWII.

ONE of the bigger problems with that design is that HV current is only limited 
by the destruction-current of the diodes: probably "quite a number" of amps, 
not milliamps.

However, there are other safety problems with it too.

Even so, in a real, life-threatening emergency, it might SAVE a life or two. It 
certainly did during WWII...

Oh...one more thing: the Dutch Underground version used 220 VAC as the 
primary...  :-(
