Turntable

[marco]

Dear Sirs

I have one problem that I hope somebody can hepl to solve solve.
I recently moved from Italy to South Korea and I brought with me my
hi-fi system, I cannot live without music , I'm an old vinyl
collector.
So...I have set up everything and when I plaied my firt LP I found out
that the turn table (Pro-ject) run much faster than 33,1/3. Can you
image, I was astonished and confused.

Now... I found out that here the electricity is 220V but at 60Hz
instead of 50Hz as in Europe.

Is that the reason ? And what I can do ?

I hope someone replay me soon.

Thanks to all

Marco

Apparently your turntable has a syncronous motor, where the speed is
determined by the mains frequency. You might find an mechanical option
inside to flip the belt to a smaller part on the motor axis, to compensate
for the higher mains frequency.

Maybe there's an alternative spindle or pulley you can fit. If no-one
here tells you (did you quote the exact model turntable you own?) ask
the makers. Otherwise buy a new turntable.

I do believe the Pro-Ject uses a synchronous motor so the speed will
be higher, yes.

>Is that the reason ? And what I can do ?

Look in the manual. It may be possible to switch the belt to a different
position on the pulley. Alternately you may have to order a different
pulley from the manufacturer. But the turntable manual should tell you.

Isn't it possible to get a power converter? Or would this cost more than
a new turntable?

I belive Pro-ject makes a Speed Box which might help here or get a hold
of Sumiko and switch motors

It's possible, but it's a lot more expensive than replacing a pulley.
Linn makes a pretty good one for around a thousand bucks that has a decent
waveform on the output.

You do understand that the OP needs to change the *frequency* (60Hz to
50 Hz) of the mains a/c? That's a lot more difficult than changing the
voltage (220v), which is the same in his home country and his destination.

The good news is that the turntable motor takes hardly any current, so
a converter can be built that only puts out five watts or so and will be
quite sufficient.

The other good news is that if you have rotten-looking line waveforms,
you can get slightly lower flutter by running the motor off a high grade
inverter that has less distortion than the power line waveform.

The best news is that such devices are commercially made, and are popular
in the high end audio world, because of that possibly reduced flutter.
The bad news is that because they are commercially made for and are
popular in the high end world, they come with somewhat inflated prices.

I used to have a Fairchild transcription turntable that had a built-in
inverter, made with a pair of 6L6es and a relaxation oscillator. Absolutely
rock solid and you could skew the operating speed all over the place.

Yes Jack, I DO understand that. If it were just the voltage, it would be
easy and cheap. Maybe 10 or 20 bucks?

Yes the frequency is much more difficult.

Certainly the manufacturer sells an alternate motor pulley for use with
60Hz. After all, the table is sold in the USA, which uses a 60Hz system.
Should cost about US$10-20.

Peace,
