Technics SL-6 Linear Tracking Record Player

This is a Technics linear tracking record player. Although it is a very old model, I have performed maintenance and adjustments within my capabilities, and it is currently operating smoothly. The program selection feature, characteristic of this model, is functional, but the timing of the tonearm lift may vary depending on the condition of the record. The cartridge is the genuine P24. I cannot comment on the needle wear, but the damper appears to be slightly weakened. I believe the playback sound is clean. Please also refer to the images of stylus pressure and rotation speed measurements.
The exterior shows scratches, dirt, and paint peeling, but I believe it is in good condition for its age (please see photos). I have also lightly polished the dust cover to make the scratches less noticeable. Please note that the cover's holding power when opened to its maximum is somewhat weak.
The only accessories included are the AC cable and a homemade pin cable (with ground wire). The record and measurement equipment shown in the photos are not included.
As this is an old model from over 40 years ago, please consider it as junk with no claims or returns. It is especially recommended for those who can perform maintenance themselves.
I will use recycled cardboard for packaging and take care to prevent damage during transport. The needle will be removed from the cartridge and packaged separately to prevent damage.
