Usually when a TOB is going you will hear the rumbling kind of noise when the clutch is depressed just enough for the TOB to contact the pressure plate. When the clutch pedal is all the way out, there should be no contact between the TOB and the PP- unless the linkage is out of adjustment and/or the entire clutch assembly is worn. If adjusting the clutch doesn't help it's probably time for a clutch, etc. If that's the case, don't neglect to have the flywheel turned. A new clutch can still slip if it's not turned.

Another thing you should check is the pilot bearing in the back of the crankshaft. It's what the tranny input rides on.
