Know before you buy
Place the disc on your platter and illuminate it with a standard mains-powered lamp while the record player is spinning. If the dashes on the disc appear to stand still, your turntable is running at the correct speed.
No, this specific model is calibrated for 50 Hz power standards. It is designed to verify 33 1/3 rpm and 45 rpm speeds under these conditions.
For the most accurate results, you should use a standard mains-operated lamp. Many modern LED bulbs have internal drivers that flicker at different rates, which can interfere with the visual stroboscopic effect.
No, you should place the stroboscope disc directly onto the platter. Adding a record on top would obscure the markings and make it impossible to read the speed.
Even slight variations in rotational speed can cause pitch instability, often heard as 'wow' or 'flutter.' Maintaining precise speed ensures that your music is reproduced exactly as it was recorded.
