My bad for not understanding what you meant by the term slip Q. If you had written it out C U E, I might have gotten the point. I thought you were referring to the fact that some early idler drive turntables, like the grease bearing Garrard 301, and possibly like some versions of TD124, had braking built into the platters so the motor had something to work against. My response was that not every idler drive relied upon such a braking system to keep constant speed. Anyway, why are you talking about disc jockeys and record changers? I did own a TD125 for several years as my only TT. Very attractive and modern looking. Performance OK. It was very de riguer in its day. Some malign it for unreliable electronics in retrospect.
