One thing you have to be careful of when transferring at the wrong speed is the playback characteristic.  Since this is a frequency curve, playing the record at the slower speed will displace the frequencies on the curve.  One way to get around this, if your amp and workstation can do it, is to record the disc flat, (no playback characteristic), and then generate the appropriate curve in the computer after the record has been brought back up to speed.
