For all those who are using B & O turntables I have discovered a wonderful company who do an excellent job in repairing and re-tipping styli. This company is the EXPERT STYLUS AND CARTRIDGE COMPANY based in Surrey, UK - contact email is: info@expertstylus.co.uk - telephone 01372 276604. This company provides you with a full written explanation of what is required for each stylus, and a quote. I have already had 2 MMC4 re-tipped and one repaired and 2 MMC5s re-tipped excellent job. Each re-tipping works out at approx. £85.
This company is responsible for looking after the USA National Record Library Collection or so I have heard. It takes approximately 1 month to 6 weeks. Covers all ranges of B & O styli repairing and re-tipping. One of my MMC4 had a complete cantilever repair, even broken off styli present no problems.
