If I remember correctly frequency voltage to power LEDs in Technics SL1210 is around 100Hz or just little more..
The function of the strobe, is to relate the rotational speed of the platter to an external reference, the power line frequency. An internal oscillator would
Defeat the purpose of
Fhe strobe. This is done because the power line frequency is extremely accurate. In North America this would be either 60Hz or multiple thereof, and in Europe 50hz. Most turntables with strobes have two patterns, one for
America and one for Europe. My thorens TD-124 for example has two patterns, and here in Canada only the 60Hz one is useful. I've never seen a strobe which acts differently. To
Get double the line frequency for an LED, it would simply involve a full wave rectifier rather than half. Now that you mention it I may have done this with my flashlight conversion. A neon light will of course flash 120
Times per second if operated at 60hz, but the pattern may stil work at 60hz since it's a direct harmonic if 120. I modified a "wall wart" type power supply to power it. Harmonics of 50hz will likely also work though .
