Anyway, I think B&O uses in Europe Axel Schürholtz needles as a replacement.
To be honest I don’t know Axel Schürholtz and I don’t want to be disrespectful to anybody, but my experience with retippers has always been unpleasant. Not in the work that as been done, but in the interaction with the guy.
This lead me to try this, and the reactions to this topic from Charte or Geoff encourage me to work harder to refine the solution until the result is enough for my needs (by fitting a better tip for example).
