I've just bought a Sony PS-1700 turntable to use to transfer all
my old vinyls to CD.
But although it played ok when I got it home, I decided to just have
a closer inspection and I removed the platter.
But now the spindle has gone very stiff and I can get it to move up & down.
Does anyone have any ideas, I can't figure out why it should move up/down

Most spindles have vertical free play. Some can be lifted right out. Most of
them sit on a ball bearing. Spindles tend to use fairly heavy lubricating
oil because they're slow moving and it keeps them quieter. As long as the
spindle feels "viscous" when you turn it, it's probably just the heavy oil
at work. It might not hurt to put a drop of spindle lube on there, though,
if you can find some. WD-40 is definitely too thin.

Thank, Karl.
It seems more serious than just in need of lubrication.
I removed the spindle (locking screw in bearing sleeve first)
Cleaned the spindle but there seems to be something missing to stop
the spindle sinking too low and causing the platter to catch on the
baseplate.
There was a lot of black gunk between the base of the spindle and
the washer/circlip at the bottom of the sleeve, I assume was the
original old grease.
Anyway I put a nut under the spindle and regreased/oiled and it seems
free and stable at the moment.

The thing that was missing is probably a steel ball (bearing) about 1/4" in
diameter.

All of the 1700's I've seen do that. At the moment I can't remember if
the 1700's had a separate ball or a rounded end machined on the
spindle.

That inside circlip at the bottom of the spindle well held a little
disk that supported the spindle. The original was a fiber or plastic
based disk that disintegrated after about 5 years.
