Thorens Turntable Speed Indicator Accessory

I used to have one. It is more durable than a cardboard one and is more likely to be flat. Otherwise, just a strobe disc.

Hi Elizabeth. It is reversible, with the "flip side" providing 60 hz! The 2nd photo in the ad shows the 60 hz side of this gizmo. Also it works with 33.3, 45, and 78 rpm records.

Dual included a aluminium strobe disc for years with their turntables that didn't have a built in strobe and had adjustable speed (1209,1218 ,etc.). Used one of these for decades until it finally became so scratched up that that I had to replace it. Bought the KAB strobe which is so much easier to use and more importantly to explain/interpret.Certain customers with OCD tendencies could get very concerned about the inherent inaccuracies in standard strobes -essentially printing error/centring issues.KAB is quick -works in any light and gives you the ability to check multiple speeds. Because the LED in this unit operates at 120hz from a battery - doesn't care about line frequency issues.

Great!! So . . . , after you learn that your TT speed is off, what do you do next, especially if it's belt driven??

Adjust it. I have several belt-drive TTs with speed adjustments.
