Can anyone help me with information on building a 9 volt
regulated
power supply that runs off 250 volts AC mains? Any help greatly
appreciated.

Thanks,
Dave

when i need stuff like this... cheap ! there are several sources.

borrow one from stuff i have allready have, go to local
salvage/second hand shop and buy it (usually small fraction of
new cost), yard sales, flea markets any used stuff sale.

the electronics may be useless but you get the part you are
wanting.

the second hand shops here usually have a 5 gallon (20 liter)
(BIN/basket) full of wallwarts for 50 cents a piece and they get
so many they dump the lot when the bin is full,
