I have one of these newer models in now, it has a problem with cut out as the jfet is not biased properly. That daughter pcb is a real mess. Besides the fact it's completely coated in non conformal dope, the surface mount ceramic caps and metal oxide resistors sound like crap and can't be removed for adjustment.
Given the choice of ordering an expensive replacement made out of the same crap, I elected to remove it completely. The main audio PCB is still the same, I just reinstalled high quality through hole components and now I can tune the jfet, which is several db less noise than whatever Sennheiser selected.
As I have done several mods to these new daughter pcb versions of 87's, I will no longer deal with that, that daughter pcb will be removed and the proven quality through hole parts will be used. The other benefit is I can now lower the self noise of the mic to around 6 db as I'm no longer stuck using Sennheiser's mystery jfet.
