Getting a Koetsu Onyx cartridge rebuilt - help


I have a vintage Koetsu Onyx that I'd like to have rebuilt. I don't want to use Van de Hul or Benz Micro because I don't want a hybrid back. Seem to recall reading somewhere that Koetsu has a service in London, or at least an arrangement with someone there who can do this type of work.

Any help would be greatly appreciated.

Found them both. HighEnd Broker has a LO XGP Reference Colibri. I have never heard of a "Reference" model in the Colibri line. I plan to contact both dealers this weekend.

Thank you for the leads.
Youre welcome

He also sells (or sold ) a XPP with platinum coils which is even more expensive as XGP (gold coils).
I would like to hear what you think of them if you by one .

Well, after all that, I have just sent a used Koetsu Vermillion and a used VDH Colibri XGM to Expert Stylus in Surrey, England for the following:

The Koetsu Vermillion: Complete suspensions rebuild, sapphire cantilever, Paratrace stylus.

The VDH Colibri: Reducing the output from .45mv to .22-.23mv, suspension tweak, sapphire cantilever, Paratrace stylus.
