I tried those PUI mics when Panasonic discontinued the WM61-A. They measure very differently. Not a problem once you determine the offsets or compensation / corrections And measure relative to your own measurements only.Check the ebay seller I recommended in FIMM. They're authentic and cheap. If he's out, PM me and I'll send you a couple.
 Where / When do I sign up?
 FYI/FWIW, I built a mic Without solder and mounted the "solderless" phantom power supply. I tested it and the kit works as well as the soldered version. Additional pictures at the link, above. ~BMF PS: I will give this "Solderless Measurement Kit" to a "starving student" who really wants to get into measurements...actual unemployed entries, only, please. If more than one person responds, I'll number each as they come in and run a random number generator to select the...
No Soldering Phantom Power Supply and Mics     See Post 1, Chapter 3   It works.
Good question. Up for grabs and testing. See post 1648, page 110 in this thread.
 Grzegorz, You're an artist And a scientist! Care to rank them for predicted sound quality improvement? If no, what are your hypotheses about the effects of the various designs?
 Annotated pictures of solderdude's Dual Phantom Power Supply are now available in Post 1 of this thread. Go to Table of Contents: "DIY Measurement Kit."
Best to build them separately in case the mic fails. Phantom Power Supply can be built Mono or Stereo.  See Post 1 for the schematic by 'solderdude' and phantom photo built in Mono. I will soon upload the Stereo version.
Better Modified Bass Ports are shown in Post 1 of this thread. You have to test various mods to find out what sounds best to you. The 1 mm dimension is the height of the slots. I seal the top 3 slots and seal all but 3 mm width of the bottom slot with the modified bass port (the opening) in the center. You don't have to remove the stock internal bass vent felt. Make a cover using thin-stiff cardboard with the 1 mm x 3 mm opening centered over the bottom slot. If you make...
 If you make many modification cycles using the screws each time, the cup threads will strip.  You can avoid this by using masking tape in place of the screws. If the cup threads strip, you can repair with superglue, let it harden for at least 24 hours, and then re-tap. Instructions are in Post #1 of this thread.
