Talon Electronics shows a Fluke FP226043 as the replacement for the MEM556C.  They have 48 in stock at $5.12 with no minimum order.

Subject: [volt-nuts] Fluke 343A part

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.
