        Don't know specifically this model, but sometimes XTALS are engraved (stamped) on the top (thin) side, or printed on one of the larger sides (could be facing the PCB ). You might need magnification to read it.

          Hi folks!
          Somebody can help me please?
          I've got an E-Mu Vintage Keys expander without the crystal oscillator (quartz) Y1 mounted on it.
          Since it's impossibile to find a schematics for this instrument, somebody of you can tell me the frequency of that crystal?
          Thank you very much.
