Is it possible?

Someone gave me a supposedly broken tape player to look
  at, and while I was doing comparitive studies with CD recordings
  I noticed that my CD player was running just a little bit slow:
  	everything was just a bit flat, and a good tape player would
 	perceptibly overtake the CD in about ten seconds.


I haven't opened up my player yet to snoop around, but what are the
   chances of me being able to tweak it up to speed?

They player is a Garrard GCD-46 boombox deal, with the CD tray on top.

If there is a simple potentiometer in there labeled "Speed Adjust", what
  can I use besides my ear to calibrate the machine?  Are there any test
  signals that a player produces (or is a calibration disc necessary?)?
I do have access to good quality oscilliscopes and the like, if I need them.


Thanks in advance for anything that will save me from 
  taking this in, and for getting this fixed before I 
  leave for home on Wednesday....
