Sony PS-X555ES turntable in box - $600 (34th st and Union Hills)

I’m the original owner of this linear tracking biotracer tonearm model from Sony’s upper echelon Esoteric Series.
This turntable is circa 1985 and was popular with audiophiles.
It has served me well over the years and is still operational, however it has developed a slight vibration; perhaps bearings.
If you need a service tech I can put you in touch with the top tech for linear tracking in the country.
Or, if you’re mechanically inclined you might be able to service it.
The turntable has been well cared for over the years and the plinth is in great shape.
Has the original box, manual, weights and adjustment key.
The dust cover has a few scuffs.
I had the original cable extended with a ground; other than that, no modifications.
Cartridge not included.
Local cash sale only - serious buyers only.
