PITCH ON 8 % ALMOST 10 MUSIC JUMPING FROM 136 BPM. - 150 BPM VERY FAST AND SHUDNT B LIKE THIS.THANKS FOR QUICK ANSWER AND I HOPE I TRY IT FIX FAST .
If your turntable is servo controlled, then the problem is likely within the PLL control circuit. Slow speeds are sometimes the result of a simple mechanical problem but fast speed usually means the servo circuit is bad. You may have to replace the servo circuit to see if that fixes it.
