Outdoor cluster lights for repair (OX1 henwood)

Fantastic set of lights, have had on our guttering about 3 or 4 years, much admired.
very upset they are broken.
Details on box in photo.
Could also be used indoors.

Beyond our skillset to repair. Have cut down the male connector part where the wire snapped but can’t access the copper wires well enough. See photos.
Giving away for repair by someone with the right skills to do it safely.
Probably need a whole new transformer/plug

Tested last weekend and working normally, but damaged when putting up.
Have another set the same are up and on. can see when collecting.
Collection only between Cumnor and Wootton.
