Unless a local dealer is willing to work on your model or else direct it to the appropriate facility for service, you could try contacting the Technics website: http://www.decks.co.uk/articles/technics_homepage

Did you buy your instrument locally or online? If locally, I'd recommend going back to them for advice first and see if they have any remaining contacts for Technics service dept.
Not sure if this is really helping you though...
