I heard of this being done with skippy records, but not this. The same 
results might be obtained by toying with the skating adjustment, then 
picking the best channel. I had one record so bad that I had to tilt the 
record player at a precise angle. It worked on a record the had the 
equivalent of Grand Canyon in it. Good ol' olde Garrard.

People with a wide choice of stylus diameters would do best at dealing 
with blasted records. You can't put back what has been taken away, but 
if there is any groove left, you might be able to find it.
