This is a sample of the original LP recording I have of Schubert's 8th Symphony performed by Wilhelm Furtwangler and the Berlin Philharmonic from about 1938 or so.  This will give you an idea of the original noise on the LP.

Schubert 8 Original

This is the "cleaned up" version of the Schubert 8th with Furtwangler and the Berlin Phil.  Note the absence of the clicks and pops and the hiss/rumble are virtually gone.  There's one anomaly, but it's inherent in the recording.  I am impressed!
