Dkarmeli, I don't own a Timeline, but I do use the KAB strobe to check the speed of my SME 30/12. It is spot on. If it changes due to temperature or belt wear, I can adjust the speed. I have read, and I have been told, that the Timeline is far more accurate than the KAB. I don't know this to be a fact. Of course, the further the wall is away from the Timeline, the more precise the measurement can be.
I did test my old turntable with the KAB and it was fine. It was also fine with the Timeline if the dot reflected on a surface within about 10" of the spindle. But once I set it up so the red dot fell on the wall about 3' away, I could clearly see that the turntable was a bit fast. It had no speed adjustability, so I could not slow it down to precisely 33.333.
Regarding strobes in general, I have seen variations. My KAB disk is slightly warped so it appears as though the speed varies at each rotation at the warp, but the numbers don't drift otherwise, so I think I'm fine. It certainly sounds fine to my ears.
I did try a hand held tachometer once and it was highly inaccurate and I got different readings by 2-5% each time I tested. The KAB is better.
I'm just curious if anyone has tested the EMT 927 with a Timeline. I'm sure it passes the KAB strobe just fine.
