Just had a play with the transformer, with 240Vac through the 380V terminals it gave secondary reading of 95V on each and 190V across both... could be usable?

Thanks for the link to the caps, they look a bit more substantial!
would something like this bit a better solution for the bridge rectifier https://www.mouser.co.uk/ProductDeta...n%2Fkm7zBfw%3D

Thanks for the photos, very handy to be able to visualise the whole set up.

I have no idea on the photos, all of mine were rotated through 90 degrees as well! I tried everything I could think of but they just revert back to side ways!
