I am looking for a 220v transformer with these secondary voltages: 2x13v, 1x9v, 1x3vIt has to be at least 20va.I cant find this anywhere :/
Transformers with odd voltages, specially with 4 windings are not really available. You need to find a different way to do whatever it is you need. Or get one custom made, expensive. One alternative is to get a 220v 100 VA transformer to, perhaps 12v, and remove the existing secondary, counting the turns. Say you count 20 turns. Then using smaller wire, wind two windings of 22 turns each, for 13 volts, one of 7 turns for 9v, one of 5 turns for 3v.
This is an unusual requirement. You may need 2 or more transformers. Do you really need the 2 voltages, or could you develop some of the lower voltage by using DC voltage regulators (if the lower voltages are used for DC)?
