hi guys,

i wanted to know where I could go to find a schematic or instructions
on building a 220V power supply. I have tried looking online...but, i
havent found anything besides a switching power supply(110 V / 220 V)

any help would greatly appreciated
thanx

Rereading this, I'm not even sure whether you have 220V at the input or
the output.

If you have 220VAC and want to build a DC power supply, the easiest way
is to use a transformer to step down the voltage (and provide
isolation, making it safe for hobbyist/newbie use), then use a
rectifier and a filter (and possibly a regulator) to get the desired DC
output voltage.

Please carefully describe what you have and what you want.
