Default Pioneer PL-512 playing too fast....

Further to the "getting back into vinyl" saga....

Now have it sounding great.... but it's playing too fast. Not by much, just
enough to make things sound a tad hurried with accompanying pitch shift.
What on earth could make it play fast?

It's not had a new belt for years, it's been stored unused for 7 years.
Could this be the problem? It's the last thing I can do myself I think
without calling in outside help. If I can find a belt that is!

Any other ideas chaps?

Hard to say what could make it go faster, lots of things will make it go
slower....

The 512 has a synchronous motor, so I would expect that if it goes round
at all smoothly, it would go round at the right speed. Having said that,
it could be that the pulley has some grot (technical term, sorry) round
it and that is effectively making the diameter slightly larger, and
hence the speed is fast. You say it's only slightly fast, so that could
be a cause.

Have you put a strobe disc on it, and measured just how fast it is
going? You can download a strobe disc from
http://www.extremephono.com/ftp/50Hz.PDF

From reading the 512 manual,
(http://www.vinylengine.com/library_m...d_model=PL-512)
I don't think there is any speed adjustment on the 512, so the speed has
to be right if the motor is turning normally.

Belt slip will show up as high wow and flutter or of extreme, slow
speed, as will a tight main bearing. I suggest you give the motor
pulley a clean with lighter fuel or isopropyl alcohol, or Wodka if need
be, and check the speed again.

How do you know it's fast - what are you using to compare?

As Serge says, there's plenty of things to make a tt run slow, but fast is a
bit unusual..???

When Pink Floyd are suddenly two frets up from concert pitch you know
something is wrong...

Playing a 33 at 45, but slowly?

Could be... there's a vibration as well, a sort of grindy hum. I thought
it was a 50 hertz hum from the power supply but you can actually feel the
vibration when you touch the deck. Perhaps the belt has shrunk making things
very tight. I will try and work out how to change the belt. I've seen them
on ebay for £6 or so.

Your right though, seeding up is very wierd.... you'd expect an old,
perished belt to slip and give loads of wow and flutter. Not a steady
speeding up. Off to order a new belt, i'll post with the results.

It played fine a decade ago. It was second hand when I got it in the
eighties but it was a good solid deck.

Hang on! Didn't the uk change from 50hertz to 40 hertz to bring us into line
with europe a while ago?

The belts on ebay have no "buy it now" option. And these people need specs

a place I can order immediately and select by model....
