Alpha depends on submissions from the public and from public data sources. As these submissions depend on the integrity of the input, no reliance should be made on the integrity of the specific data points. However, those who desire to update or remove a listing may do so through the Alpha 400hz Repair update page using the TryAd Directory Management System (TDMS).
