I realized my PDM coils will be too big to fit in a new PDM tube rig I'm building. Does anyone have the PDM coils or complete filter they might like to sell? Some are layered and quite small. Some use ferrite and some use air. I will put them to good use!
If you know of any BC surplus places that might have one, please let me know.
Thanks.
