I agree with Ken. Be aware too, that some re tip jobs consist of gluing a new cantilever/stylus assembly where the old one makes its exit out of the generator. This makes the business end new, but does not address the problems of suspension, and integrity of the original design. Not the same as a rebuild by Musical Surroundings, particularly if the Koetsu makes the trip back to Japan.
Koetsu cartridge rebuild
I have an older Koetsu Rosewood and was wondering if anyone could recommend someone who rebuilds these things. I've never even thought of doing this before, but I see fairly often where somebody is selling a retipped or rebuilt cartridge. Any help would be greatly appreciated. Skip
