I'm thinking of getting a 1002 2555x Jubilee from the UK and changing the input transformer so it runs on 120v here in Canada. Providing I get the correct part, how easy a swap is this? When I did my 1w combo this way all the connections were push on spade connections so it was super easy. Does anyone have any experience with these heads? Are there any photos of the insides anywhere? I'm hoping it's a solderless job that can be done easily.
