Going through my spare parts box as I need to get rid of things before I move house. I have 2 c64 220V PSUs that are fully functional, coming from broken c64s I scavenged sids from. Not useful in the UK since we are 240V so the AC out on these are too high for a C64 without a step-down transformer.
So if you are after C64 supplies for your midibox sid please PM me and I will send them to you for whatever the shipping costs me - uk to mainland europe - I estimate it would be around 9 euro, judging from shipping prices to the UK for similar items. They will end up on ebay in the next few days if no one wants them.
