Akito Kaneta, a japanese professor known for his Kaneda amplifiers invested a lot
of thoughts in modifying the Technics SP-10 family. This resulted in a unique
motor-control-circuit and plans for building a suitable plinth for the deck.
Thanks to Mr.Aschenbrenner from Auditorium23 for
the material shown here.
These circuits were published by Mr.Kaneta in one of his books around audio electronics.
You can find the relevant passages (all in japanese), circuit-diagrams and layouts
Instead of a quartz-control a quite advanced frequency-generator for the reference signal is used.
This motor-control is especially suited for upgrading a Technics SP10Mk1. Note that there
might be problems to get hold of some of the older components used here. The circuit-diagram:
The SP-10 was stripped off, all electronics are located in a separate housing.
Like many japanese audiophiles Mr.Kaneta preferred the old faithful SME3012 tonearm.
The plinth pictured here was made from lime tree wood after the original plans
A lot of wood:
