Fluke 5500a Calibrator repair,    help with  Fet or transistor IFC07703 ?

Trying to solve some issues with a Fluke 5500a Multi Calibrator.

Error codes on the A5 Impedance Synthesizer board:

Trying to find Fet part # IFC 07703 !!  { listed as Q3 & Q4 in Fluke 5500a manual... no schematics either !! }
in a TO-92 plastic package, also can't find data sheets for this Fet or transistor !
