Even more interesting.
The design where the Stator / Platter Bearing Housing is embedded into a Chassis/Plinth on a SP10 is commonly known of as the Kaneta Design and gives credit to the creator Dr Kaneta. There are today a few Variants of the earliest of designs.
I am a variant of this designs produced using Panzerholz or Permali for a SP10 MkII (the new TT is now purchased to be donated for the build ) and a friend has already got their one produced, the only delay at present is the New Power Supply being produced.
I have encouraged this route for quite some time, as I have first hand experience of the PTP Solid Nine which creates similar for a Lenco Idler Drive. The PTP and Kaneta shares a similar design intent and I can't help but feel quite sure the notable merits for the Lenco Idler Drive mechanical interfaces will transfer over to a DD TT.
There is plenty about this design on DIY Audio to strongly suggest a Kaneta variant it is a valuable addition.
