Oktava Microphone Modification Services
You can do the
modification 3 ways for the MK-219:
2 - I do an electronics only modificaton service for $74.
The 219
electronics mod kit contains all the components listed below. Detailed
step by step instructions, like those provided with the 012 kit, are
not included with the 219 kits. Pictures showing all the part placement
are included. 
Major changes come from
modifications to the body and capsule basket. Just hold a 219 in your
hand and tap the basket screen with your finger. You will hear it
"ring" and feel the vibration in your hand. As part of the
modification, damping of the body, and
isolation of the capsule, virtually eliminate this. The outer basket
supports of the case are removed.
The capsule diaphragm resonator discs are removed. One layer of
capsule basket screening is removed. This opens up the basket,
minimizing sonic reflections and
reduces some "ringing". Normally the capsule diaphragm resonator
discs are removed. This is optional, removing them provides a warmer
more rolled-off top end, they are intended to trap the high-freq
and
extend range. I prefer them removed.
All critical electronic
components are upgraded to quality parts. Polypropylene capacitors are
used in the direct signal path. The improvements in the electronics
increase the high and low end
response, flatten the response, increase detail, warmth, and provide a
lower noise level.
The low cut and attenuation switches remain functional on the 219,
although I don't recommend using them. All removed parts and
components are returned to you (removed screen is not
returned).
In Summary:
The body is damped
The outer basket supports of the case are removed
One layer of head basket screening is removed
The capsule is isolated from Vibration
The capsule diaphragm resonator discs are removed
Damping material is added at the base of the capsule
All critical electronic components are upgraded to quality parts

A
difference you can Hear!
"I just wanted to thank you again for mod'ing my 319. I was able to do
more recording with the mic today and I have to say that I really love
it! Before I had you work on it, I would take it out, give it a try on
some tracks, and end up putting it back in the drawer and re-recording
the tracks with a different mic. You've made this mic into one
seriously great mic. Where the sound was muddy and distant even when
practically eating the mic, it's now clear, yet with that nice, warm
sound that the 319 has become known for. If this is what you call a
significant difference, I can't wait to hear what you call a dramatic
difference when I send you my 012's."

"I finished the mod on the weekend. This was my first electronics
project in a very long time, so it isn't pretty, but the results are
amazing. The thing I notice most is the difference on sibilant
sounds. The combination of physical and electronic changes removes the
"esh"ing that I notice on most mics below several hundred to even a thousand
dollars. I used to have to put in de-essing plug ins to compensate.
Now I can just enjoy the sonic characteristics of the recording. There are other
qualities that I'm noticing too - changes in the frequency range and the like -
that I'm still getting my ears used to. They're hard to describe, but make
the recording far more pleasing to listen to. Thanks for all of your
help."

"I wanted to give you an update on the four
319's you help mod for me. To refresh your memory, I did the physical mods and
you finished them off with the electronic mods. Anyway, I have used them for
multiple purposes, two point stereo, guitar/bass cabs, piano, drum OH's, and
more and they have performed very nicely. I have used them with some big dogs,
i.e, Schoeps ccm4's, Neumann SM69, 103's 184's, AGK 460's Royer ribbons, etc,
and they have fit right in. I can't believe that for so little money I've ended
up with such a great mic. I bought four of them new for $79.00 each and after
the mod I've got $200 into each mic. They certainly outperform this price point
and much higher point. My next step is to make a damping corset, made out of
leather, to wrap around the outside of each mic. I think this will really damp
any resonance problems that remain and should look great, too. Finally, the
proof is in the pudding. Almost all my recordings have at least two 319's in use
and my clientele have thoroughly enjoyed their recording and have showered me
with praise."

"Hi Bill........Got my mic and I love it. I had
to do some experimenting at first as to how to position it. Before, I got a
better sound straight up. Now I get a better sound having it hang down. The big
thing I notice is the highs are super crisp and don't splatter when I throw a
little EQ in post. The base is nice and tight and if I really get right on the
mic, the (in your face) sound is probably the best I've ever heard. I take it
that the spare parts are what you took out of it? Thanks again Bill. It really
sounds awesome. I can't wait to show my friends who also have
MK319's."
"Van Ritshie here. You recently did a mod to my MK319. You mentioned to
me that the mic would get better as time went on. Let me tell you Bill, at this
point in time I could not be happier. I've had a lot of compliments from people
I do steady VO work for on how my spots are sounding. Again, thank you Bill for
a great
job."

"Hi Bill, You did a terrific job! I am very pleased
with the outcome of my Oktava 219 modification. I did a series of comparisons with my other
mics which I think are very good microphones. The Oktava mod is very in
your face with enough upper mids to set well in the mix with very good articulaton.
For MY vocals, it really shined and I'm sure it will shine on acoustic instruments
as well because of the emphasis on the frequency body were vocals
and especially acoustic instruments live. Thank you so much for making me a great microphone. It's
even better than I thought it would be....You ain't heard the last
of me!"
