I think I may have given this contact in reply to an earlier request from you:-

Tape Recorder Centre (Colin Braddock)

266 Waterloo Rd
Blackpool, Lancashire
FY4 3AF

Phone: 01253 345049

I haven't used his services for many years, but the shop was still there when I passed a few months back. Competent servicing, fairly expensive, but then most of what he is working on was top-of-the range twenty or thirty years ago (and can be brought back to full effectiveness in the right hands).
