Hi! Anyone have any experience with these mics? People on the interwebz seem to think they are useful especially after the Dorsey or Joly mods. Oktava MK 219. A client just gave them to me. They don't work. I'm pretty sure it's just the FETs that are zapped so I order some replacements. I will update when I get them up and running. I think I'll do the above mentioned mods on one of them and post direct A-B samples. Cool?
