Question about Numark PRO-TT2 Turntable

1 Answer

Turntable probems I have a pair of Pro-TT2s. One of them speeds up sporadically of its own accord. I thought it might have been speeding up between 33 & 45 rpm, but itseems to go even faster sometimes.

Re: turntable probems

Belt or belts needs replacing. Happens when they get worn. Happen a lot in the days before CD's. Fairly simple to replace if you are mechanically inclined or have some one do it for you.

The turntable runs great for half the way throw the lp and then it speeds up to a 45 speed

Any infinitesimal change in belt temperature would not cause such a change in speed. The speed of your turntable is governed by an electronic circuit and this is where the trouble is.

The cost of a repair is going to be mostly labor which may exceed the value of the value of the turntable.

Bush MTT1 turntable - does it contain a pre-amp?

Yes, according to someone else online who owns one:

"It is a simple device (I have one)

33 or 45 rpm
Pre-amp on/off switch underneath.
Two leads out.
Arm up/down lever and slight speed control.
When the light are stationary due to strobe effect then the speed is right."

Sony hmk-v82 turn table speed. The speed changes slightly all the time, tone in music goes up and down accordingly. What is the solution?

This is known as wow and flutter. It's generally caused by the belt being lose on a belt drive turntable or the motor on a direct drive one. The motor can cause it too on a belt turntable!

Deck speed up to uncredible speed and wont stop

You both have issues with your drive circuits. There is no easy fix for this. You will have to take it to a repair center to have them serviced.

There are 4 main Integrated Circuits that control the speed/drive and any one or all may have gone bad. We are seeing this alot with these units now.

Wish I could be of more help.

The drive circuits on this unit are probably failing. Have you had any service done to it recently, or at all, ever? If so, this might be the problem. The caps have probably dried out. Once they dry out, they go pretty fast afterwards causing variance in speed. A good tech should be able to replace the caps, and get your unit back to original specs.

This is a drive issue. You will need to have it professionally serviced, as there are many issues which may affect the drive of this unit. FYI, there is no 'motor' in a direct drive turntable. It is driven by various circuits on a circuit board, and if any one of them goes bad, your drive will be affected. The issue could also be a faulty pitch control as well.
