The motor for the unit might be dying out. There really aren't any other factors that control the speed/rpm of these belt driven models. So if the belt didn't do the trick, you will have to take it to a service center to test the motor.

If this is a belt drive turntable the belt might be in the wrong position or is slack due to wear.

2 problems, 1st turntable run at 45 speed when on 33 setting. 2nd, turntable won't move unless you help it.


It depends if these are belt or direct drive decks. If they are belt, then in the first fast speed one the belt might have slipped and is now on the 45 setting when it should be on the 33 setting.

The other deck has either a really **** belt, or a bad motor, or needs oiling or having grease or muck removed from it's works.


A whole list of problems can make direct drive decks act this way.

How can I get it to play 33 1/3 rpm?


All turntables have a button or switch that will select that speed. If that doesn't work, you have either replaced the belt wrong - on a belt drive model, or you have an electrical fault on a Direct Drive type.

Why is this turntable running slow?


It depends which type of turntable it is. If a belt one then change the belt, make certain you make a note of how the belt fits before removing it.

Direct drive turntables are more difficult. As it could be any number of faulty parts that cause it.
A build up of grease or dirt in any type of deck can slow the speed down.

A faulty motor on both types of deck will also cause it.

Grundig 4400 / Audio Techinca T4P Turntable spins at 35 RPM instead of 33 RPM


I think you mean 45 rpm?
It sounds like you have got the belt in the wrong position. Try adjusting the position of the belt by experiment. Or you could look up the correct way to set up the belt.

possibly your capstan needs cleaning? remove the platter and locate the capstan which is usually made of brass? if it is dirty, ie; black use cotton balls and neat alcohol (spirits ) to clean it. also, consider changing the belt as it may have stretched?

Speed control issue


Not sure I understand what you need done. The 1200 has a pitch control, which allows you to control it's speed. Do you want to disable the 33/45rpm function, and assign that to the pitch control, so instead of controlling pitch, you control the RPM? This will put quite a strain on the drive circuits of this unit, but it can be done. Although, not an easy modification, as you will have to modify multiple resistors and IC's on the main board. This should only be professionally done.

JVC Turntable model AL A1 BKX , need to know how to adjust speed


I have just fixed this problem on my Aiwa PX3800 with improvisation.
The platter was rotating too slowly, I didn't know how much too slow only that the records sounded wrong.
I imagined the belt, motor and platter as a bicycle gear and so simply increased the gear... I achieved this by winding a thin strip of a electrical insulation tape around the motor head to increase it's radius (like changing up to a larger front cog on a bicycle gear).
I could then time the rotations and remove a layer or two of the tape accordingly until I have achieved a perfect 45rpm. 33 is still way out but I only listen to 45s!
Be sure to trim excess tape from the motor head with a craft knife/scalpel or it'll stick to the platter.
Poor man fix up.
