I picked up a fairly new Fluke 343A and it appears that Q39, MEM556C p-chan. enhancement-mode MOS-FET is shorted. This part seems to be unobtanium unless you are named Romney, Gates, or Walton. Any suggestions on a replacement or an alternative method? This part is the input signal chopper transistor, driven by a multivibrator.
