Re: [ARSCLIST] lacquer transfer

[Eric Jacobs <EricJ@xxxxxxxxxxxxxxxxxxx>]

Transcription discs (aka lacquers, instantaneous discs, 
acetates, etc.) are too fragile and prone to damage or loss 
if not handled properly.

I collected some of my thoughts, research and experience with 
transcription discs into a webpage that I hope people will
find useful and may prevent some inadvertent damage:

Seems more than a little invasive to me. I think a pass with a  
trusted (read: mild) cleaning solution in a K Monks is about as 
far as you want to go with regards to anything wet.

I'm all for doing whatever you can to secure a quiet capture; among  
other reasons, to avoid the need for excessive digital "cleaning" 
in post. Thinking long-term however, coating or spraying a disc to 
make it quieter at playback sounds like it introduces more
problems than it stands to solve..
