Turntable playing to fast

[admin_exported]

Hi everyone im new here,

I have a speed problem with my Kenwood KD491F the belt is the correct size when i put a 12" on it plays but its to fast and it is on the 33 setting. But when i put a 45 on and play it at 33 it plays perfect but not on the correct speed of 45.

What could this be ?

Thanks for your time

It could be one of several things generally. I'm assuming it uses a small DC motor with either a built in or "separate" speed regulator. Separate as in separate from the motor. Unfortunately this forum isn't really the ideal place for this kind of issue. To diagnose would involve at least some dissasembly and basic checks.

Thanks for your reply oh right okay what forum do you think would be a good option?

Many thanks

Hi mattt_bugs. It may be a silly question, but have you checked that the voltage selector is set to '220V' not '110V'? I'm assuming you are in the UK.

there will be a couple of trimmers on the circuit board, one for 45rpm and of for 33. If you look under the base of the turntable, there may even be little holes allowing you to adjust the speed from below with a small screwdriver. To get the speed right, you need to obtain a 50Hz strobe, or print-out a scan from one, such as this: http://members.multimania.co.uk/willbewill/GL75/strobe50hz.jpg. Pretty obviously, you need to set it using a 50Hz artificial light.

I was wondering if you have had the Kenwood for a while and it was ok but isn't now, or if you have just got it s/h? If the latter are you sure that it was designed for the voltage of electricity you are using; e.g., aa TT made for the US market will be highly unlikely to play at the correct speed in the UK and vice-versa?

If the voltage was set to 110V and he's here in the UK on double that, I'd expect something to go KABOOM and not just play 33% fast.

Worth checking though!

You can buy a strobe (Superfi sell them) or maybe print an image off the net.

Sorry, couldn't help it!

No offence, mate, but unless you know a fair bit about elecronics you could be in for a lot of trouble. My guess would be it's something in the power supply, and I reckon it wouldn't be worth taking outside to be fixed. You'd be better off looking for a secondhand Technics, or getting a new AT or Dual turntable.
