Re: [ARSCLIST] [AMPEX] Loss of Lubricant and A- and B-winds

During the squeal , the tape will oscillate in sync with the squeal ,
and severly distort the new copy. Filters won't work for that
application. 

Especially true when SSS is the cause of the squeal.

Be very careful about playing a squealing tape at all without 
lubricating it.  I've actually had squeal print to tape!!  This was 
years ago when I first encountered the problem on a VO master recorded

on reused tape of unknown origin.

Since then I have encountered only a couple tapes with the problem and

have used my own primitive methods to re lubricate.  I've been very 
interested in what others have come up with.
