Clock Frequency of KRELL SACD Standard Player

It is the old KRELL SACD STANDARD Player using Philips Transport. I ask the question, because I am thinking to replace the clock with SuperClock 3. I have to provide clock frequency in order to buy the Superclock 3. I am looking for the clock frequency that use to Play Stereo SACD in the KRELL SACD STANDFARD PLAYER
