Chinese / Russian swaps
Crazydoc -
too bad I don't have a dig cam. I've been doing similar swaps and mods...
1.) I put an Oktava MK-219 capsule in a lollipop head grille sitting on top of an MXL V63 Fet amp.
2.) Put the MXL V63 capsule / headgrille on top of an Oktava MK-012 head amp via the -10dB pad converted to 0 dB attenuation - ( just used as a electro-mechanical connection. Looks sort of like a Geffel UM70. I've also done a version of this with the MXL V63 capsule / headgrille driving Dave Royers 5840 cathode follower circuit installed in another MK-012 body.
re: Oktava LDC black plastic HF boost discs - I posted quite a bit of info about these on rec.audio.pro (do a search on my name and Oktava) The discs boost HF by 4dB at 10kHz but they smear the transient response. I prefer the lower HF but better time alignment when the discs are removed.
re: Piotr - you might want to cut out the grilles of the MK-219 body you're using. these mess up the clarity of the HF due to reflections and refractions.
My headgrille experiments have taken this path to greater claritiy - first I cut off the MK219 grille fins, then I pulled out the fine wire mesh of all my mics that use a double layer of wire mesh and just left the larger gauge wire mesh intact, next I removed the head grille of the MK319 (which also exhibits a ringing resonance when tapped) and replaced it with an ELA-M 251 style, single layer mesh. Much better transient response than the stock MK319 head grille.
My most recent experiments have been turning MK319's into lollipop bottle style mics. I seem to prefer the open sound of minimal reflective and refractive surfaces around the capsule.
oh...I've also been experimenting with conical-shaped foam inserts that cover the flat base capsule mounting area and rise to an apex just below the bottom of the capsule. Again, seems to minimize HF annomolies due to reflections in the capsule head.
