When I press play, the reading goes up to around 7.2 to 7.5KHz and more at times. Even though I select different speeds, the frequency...

    Studer A807 motor problem

    Hi I am having a problem with my studer. When I press play, the recorder does play, but the take up motor (right hand side) moves slower than the supply motor (left hand side). What happens is that the excess tape from the left reel gets stuck into the reel. It looks like both the motors are...
