JA Michell Hydraulic Reference Turntable

Working original JA Michell Transcriptor Hydraulic Reference Turntable made in the early '70s.  Serviced last year by , hydraulic fluid replaced, new grounded power cord, new stylus, drive belt and rubber feet installed, set up and tested. Very clean, missing the vinyl brush. Includes all shown. 

Prefer local pickup if at all possible, because turntable is pretty heavy & fragile. Also, the hydraulic oil reservoir would have to be drained for shipment.

Fluid Arm Description:
The Transcriptors Fluid arm has been developed specifically for use with modern cartridges of not more than 16g weight, tracking at no more than 2g.
It employs a unipivot working in an oil-filled well, so that the arm beam assembly relies for it's lateral support, stability and resonant damping on the fluid surrounding the pivot.
This results in a substantially friction-free pivot of high stability.
An adjustable eccentric counterweight allows both lateral and longitudinal balancing of the arm.
Fine control of longitudinal balancing to allow adjustment of the stylus tracking force within a fraction of a gram is provided by a screwed counterweight.
Also provided with the Fluid arm is a bias compensating device so designed as to use a rolling motion.
An adjustable bias weight operating through a pulley gives correct compensation as the stylus moves towards the centre of the record.
A lifting and positioning device is provided incorporating a hydraulic lowering hand wheel which lowers the arm onto the record automatically, but which can be over-ridden when required for accurate manual positioning.
A plug-in headshell is fitted for mounting the cartridge, no soldering is required, and the signal outputs are taken via a pair of 3-feet long screened leads terminated in co-axial plugs.
