[QUOTE="Sarel.wagner, post: 1134566, member: 25509"] Me, to lazy for all that, and besides, I maybe remember after a few days that I forgot. Tried to manually log them hours, unreliably. Something along those lines fdlsys yes. Considering manual TTs as well. A definitive way to detect play time is the audio signal. No music output from the preamp (voltage in the cable), and the arm home or platter stationary, no stylus wear…. Not so definitive is the platter spinning and the arm not at rest. For manual TTs, even if the runout groove is spinning with the stylus still down, its still running up the hours. So we now know if the platter is not spinning, not playing, and if the arm is home in storage, we not playing or racking up those hours. The logic dictates that we can only have hours going up if the arm is not home, the platter is spinning and we have a output signal above a base level. Sounds about right to me, care to comment on the logic? Both the spinning platter and the arm at rest can be sensed simply. We can also tap in to the signal easily, thanks to project 38, thank you handsome. Groetnis [/QUOTE]
