Need oktava mkl 2500 CF version schematic

[spiders]

Hello there. I am a long-term lurker on this board, and would like for my first post to not be a cry for help, but here I am. I have recently gotten into modding microphones, I have an Oktava MKL 2500 cathode follower version that I don’t use and so I thought “hey let’s pop in some different components and see what happens” Unfortunately, the capsule to tube cap fell apart when I was removing it. I’m good at soldering/rework, this cap was just really poor quality I suppose. Leg fell right off. Anyways, the cap has no markings and I can no longer measure what it was.
Does anybody have this schem any more? I’ve done quite a bit of googling and have only come up with a hand drawn version of the PF mkl2500. Thanks everybody

1nF / 100-250V should be a pretty safe bet, to start with. Rarely seen higher values, and even more rarely lower (U87 uses 470pF, iirc?).

Thanks a million, I’m sure I have one of those laying around. I’ll report back on whether the mic explodes or not

For those waiting in the wings and wringing their hands, the patient survived and is actually better for the experience
