Richard,
Somebody passed this information to me early this year
Jim Carroll

Jim - Mr C. Braddock at the Tape Recorder Centre in Blackpool, Lancashire used to keep my Tandberg reel-to-reel and cassette machines working. He usually had Uher, Ferrograph and Revox machines of various ages in stock, so I guess he could cope with any machine you need working on. My machines haven't needed his attention in recent years as they are getting used less and less, but he still appears to be operating from the same shop;-
