Roksan Kandy MkIII CD Repair

Hi. I am based in Lutterworth Leciestershire. I have a Roksan kandy MkIII which has a Tentlabs clock & PSU following mods by Colin at Chevron Audion (Derby). It has just packed up with a blown fuse but with no obvious damage to the internals. I have replaced the fuse with the same result. Does anyone know who would be able to look at it and comment on & carry out any repair. I am happy to travel etc. I have emailed Colin but I'm not sure if he is still active. I was last in touch with him 5 years ago. Many thanks Adrian.
