Distorted sound on Technics SL-1200/1210


You could be getting acoustic feedback from the speakers to the TT's. Lower the volume or somehow isolate them from room sounds and vibrations.

Just bought a new technics sl-1200 turntable and the pitch speeds up and down causing music to sound funny....


You will need to check your belt for wear. Lift felt on platter and check belt tension. It may need replacing. To replace, simply lift platter section of the unit, taking note of the belt position. replace and your problem will be solved

It sounds like you need to replace the belt. If it's too loose, it will not maintain the proper speed.

When i turn on my technic 1200 turntable it the lights flicker and looses audio sometimes


Hi, i doubt the 2 are related as the T 1200 doesnt have a preamp, only speed control.

Maybe try checking to if there are any loose ground wires in the turntable (ONLY if you are comfortable to open)

Other than that it the sound issue might be either on the head, or on the phono outs not connecting properly.

If the speed is remaining good, then the issue is just with the LEDS themselves, maybe loose solder, if it is changng pitch as well, then dry joints in the power supply/pitch control

Hope that helps

Counter clock spinning


pitch slider can cause an unstable motor (clean with can of air and switch cleaner) if it spins counter clockwise it will be the brake. there is a little screw in a hole under the platter to ajust the brake speed.

No control of platter speed


One of the drive circuits on the main board are faulty, and will need to be replaced. This is not an easy fix, so you will need to take it to a qualified service center for service and repair. Not an expensive fix, but a little time consuming in isolating the issue.

Technics 1200sl pitch control


There seems to be 2 issues with this unit. Usually when the platter speeds up very quickly, one of the IC (integrated circuits) are faulty and needs to be replaced. However, I've never seen the 33/45 lights come on in addition. So, perhaps the issue started with faulty 33/45 switches, and it then caused a short to one of the IC's.

This will have to be professionally serviced, as it is not an easy fix. There are various circuits on the main board which control the drive, so it's a matter of diagnosing which is the culprit. The 33/45 switches will also need to be tested/replaced.
