The device is in good cosmetic and technical condition. Fully serviced and working. All functions work as expected.
The heads are in good condition as seen in the photos. full inspection done. All belts and rollers replaced,all mechanisms are greased and cleaned, heads  have corrected by TEAC TEST tape,tape patch tested! Motors are  cleaned and tested on full working condition.
RECORDING BOTH DIRECTIONS!! 
PERFECT RECORD SOUND OUTPUT...

White edition!!
Have few more these reel to reel decks in stock as soon sold this one will upload another stay tuned ,also have all spare parts for these machines X10/X7/X1000/X2000/Tascam 32 

Direct import from Japan recording studio: (better build than EU version,quality on components are more high and longer life)
Japanese version of 100 volts. replaced to 230V transformer,to use in UK or EU!!!

This is a tape deck that can record and playback the X series 4 track No. 10 reel back and forth.
It is a reciprocating recording and playback machine of Reel 10, so it can record 3 hours at 19 cm/s and 6 hours at 9.5 cm speed.
A dual capstan system is adopted for the mechanism part.
This system has a structure in which two sets of capstan and pinch rollers sandwich the tape and drive it, thereby greatly reducing modulation noise. In addition, since tape tension is given by the slight rotational difference between capstan and capstan, even minute tape vibrations (flutter components) that do not appear in the catalog data are shielded.
In addition, due to the symmetrical design, even in reverse operation, the same conditions as in forward operation are obtained, and uniform tape travel is achieved in both directions.
A magnet-float type flywheel is adopted.
It is designed so that there is no play in the axial direction of the capstan by pressing it against the bearing using the repulsion of the magnet, thereby realizing stable rotation of the flywheel.
The head section is composed of 6 heads, and each head for erasing, recording and playback is independent of each other.
A high-hardness Permalloy head is used for the head, and an erasing head, which does not affect the sound quality, is placed outside the closed loop to shorten the tape span.
The amplifier circuit is designed with dedicated adjustment circuits for both the recording and reproducing heads to reduce the difference in sound quality between forward and reverse.
You can set timer recording in either direction by setting a timer switch in the center of the front panel and a commercially available audio timer.
Equipped with a 1-3/2-4 track selection queue mechanism, you can queue the necessary songs without switching tapes.
When the driving indicator lamp for either the forward (1-3 track) or reverse (2-4 track) track is on, queuing can be used to start the track.
Equipped with a playback pause mechanism.
If you press the pause button after getting a rough idea with queuing, the tape touches the head, and you can turn the reel with both hands to get an accurate cue.
Uses an electromagnetic brake.
Equipped with a motion sensing mechanism, if you press the play button directly from the quick turn, the electromagnetic brake acts on the reel, it stops softly and moves to play action instantly.
When the Oatley bar knob is set and the counter is set to 0000 and the tape is played back, it can be automatically reversed from the reverse direction to the forward direction at that position. Only by combining this function with the Oatley bar, you can play it endlessly all day.
Equipped with Rec Mute function.
It is equipped with a real-time pause function that makes it easy to rise from a recorded pause.
Microphone and line mixing is possible.
With a guide roller mounted, smooth running characteristics are achieved by absorbing uneven running of the tape.
Equipped with reel size selector, suitable tape tension can be obtained according to the reel size.
Equipped with a pitch control function that works for both recording and playback.
Equipped with an L/R linked recording mode switch.
Equipped with independent bias and equalizer switching functions.
Equipped with a large VU meter.
All-DC motor configuration is adopted.

Since the device is around 40 years old please expect this

I pack very securely, I use two boxes and a lot of styrofoam and bubble wrap.
