[sdiy] new zealand electricity ??

Hi Peter,

If you've designed a linear regulated supply that could be on the 
borderline for regulator dropout voltage then it could be a bit worse 
with 50Hz supply as there  is more time for the filter capacitors to 
discharge before they get topped up again. I think this would be 
insignificant if you've left plenty of room for supply voltage variation.

I've seen all sorts of 120V/60Hz gear running fine using step down 
transformers. (I live in Australia where it's 240V 50Hz)

Cheers,
Stew.
