I am based in the UK, and not aware of a forum member known as Alexy.
The Tonearm I am referring to is at present a prototype, that has had a quantity of critical parts requiring outsourced machining, as it has been cost effective to do so, instead of having one part only produced.
The designer and builder/assembler also has the skills to machine a selection of the parts, but those parts that have to be 'minute dimension accurate' are best left to the services that work with the producing the tightest of tolerances daily and know the best practices.
The Geometry and Mechanical Interfaces are complete for the Tonearm.
It won't be long before the mechanical interfaces to be considered for the TT assembly of parts are to be addressed, and the Cart' alignment is given a extra TLC.
Then when all is ready and functioning as designed for, I will request that a second Tonearm is assembled with PC Triple C Internal Wire, as my most recent experience has shown that there is a special attribute for this wire when used as the signal path within a Tonearm.
I am hankering for, and really looking forward to the time when a Company produces a Cart' with this wire used for the coil and Lead Out Pins, it might just prove to be a New Break through.
