Conrad Johnson PV14 Pre amp rewire questions

Anybody has experience relating to rewiring the jumpers in the CJ PV14 pre-amp power supply to make it work under 220V? I have moved abroad and want to rewire it instead of using a step-up transformer.

Thank you!
Anybody has experience on the subject matter?
Got it resolved last night by myself. 6 sets of wires needs to be rewired.
