I've found this psu by Tony Van Roon : **broken link removed** But it's rated for 115V. Is this suitable for 220V without major modifications ? Thank you for your help and suggestions.

Select a similar VA rating but a primary voltage of 220 V AC. (of course, you have to use the same secondary voltage as indicated on circuit). Regards
