Re: [ARSCLIST] Question re DuoDisc records

[Steven Smolian <smolians@xxxxxxxxx>]

You may be able to get some of it back by putting a bit of vasolene un the 
underside of the lifted sections- just a bit.  You can then line up a groove 
and, if it becomes too discontinuous, you can slide it over a hair.  Record 
what you are playing on a hard drive and paln to do considerable editing.
