Recently, the technology has fallen into the hands of "the consumer" or "audio-phio" or "archivist" to transcribe analog recordings into digital CDs which may be played on any traditional player (WAV)

You will find the most current information and the highest interest levels in the "news-grouops" of the internet. A great deal of trading occurs within the obscure recordings because they are not available through any other medium.

If this is your interest, I will post some of the groups that may benefit you.
