B. Drift Study 14 VII 73 9:27:27 - 10:06:41 PM NYC Three sine waves. Frequencies and voltages of the sine waves determined and tuned by La Monte Young using oscillators custom designed by Rober Adler to generate specific frequencies and voltages of great stability. Performed 14 July 1973 at La Monte Young's private studio.

For the maximum fidelity on Side 2, reduce the treble controls on your pre-amplifier to minimum. Since the sine waves have no harmonic content, and all are below 202.5 Hertz, this will reduce the surface noise which is normal on most discs. Note: Be sure to keep the treble controls normal on Side 1.
