Sony PS-X800


The Sony PS-X800 features a unique servo controlled linear tracking tonearm designed to duplicate the movement of the head which cuts the record master.

Compared with a pivoted arm, a linear tracking arm has a very small tracking error which means greatly reduced harmonic distortion, improved tracking ability and channel separation.

The horizontal and vertical movement of the tonearm are monitored by Sony's Biotracer sensors, and this information is transmitted to the tonearm by linear motors to suppress resonance at low frequencies and to obtain the maximum signal to noise ratio.

The tonearm balance and stylus force are electronically controlled by adjusting current to the linear motor for vertical movement.

The PS-X800 is a fully automatic system with feather-touch controls.

Record size is automatically set by a photo sensor, a muting system is activated when the tonearm is lifted and speed and direction of tonearm movement are easily controlled with the arm direction and fast buttons.

The unit is powered by Sony's linear torque BSL motor with speed governed by a very stable quartz oscillator and magnetic speed monitoring system.

The PS-X800's cabinet is made from a special inorganic (non-plastic) moulded compound with low 'Q' and newly developed resilient feet, effectively minimizing outside vibrations and acoustic feedback.

In some respects the PS-X800 was quite a good turntable, with the present arm probably the weakest link. In truth however the performance was little better than the less costly PS-X600 - £375 HiFi Choice 1983

Audio and the PS-X800

I'm having trouble getting audio from the player.. What kind of speaker/audio device does it need to connect to, exactly? I can't find any information on this.

how knows which needles or cartridges are compatible with the sony ps-x800?

i want to get one and can't not find accurate info about this.

appropriate cartridges for PS-X800


in principle are suitable for PS-X800 with its regulated control and active damping of the arm all phono cartridges.
The active control and damping of this Biotrace arm is in contrast to a normal passive tone arm
completely independent of the otherwise required match between the compliance of phono cartridges
to the resonance region of the arm weight.

So you can go to the search for a good cartridges without which the suitability of a particular tonearm in your way.

servo? questions

the arm not lowering
when it is supposed to, but it appears to show when the unit have a
bit of time to warm up (setting it on repeat and it will get stuck on
the second run). It appears that when the unit homing in on the first
track, it will first move into location fast, and then the motion will
change to very slow movement, and then the arm will drop down into
location. When it doesn't work, it stopped right after the fast
movement into location, the slower fine movement never occurred, thus
the arm never got to the part to drop down. I can drop the arm down
via the control if I first shift the head left/right a bit via the
button, and then I can drop it down using the up/down button. (the up
down button won't work if I didn't first move it around a bit with the
control) Ideas??????


There are TWO motors and two belts which drive the arm - the belts could easily have sagged iin the last 27 years!
On my deck one of the arm motors had worn its nylon bearing and was jammed. I separated the motor into two halves, drilled a hole and replaced the bearing with a nylon screw. I also needed to adjust the voltage regulator as the main board was running on about 1.5 volts as opposed to 5. You have the manuals to help you here but this is probably the most complex TT ever made - and certainly one worth persevering with - good luck!
