Up for consideration is a rebuild / mod service
for your vintage Neumann Gefell CMV-563 tube mic. The
mod includes replacing the old, low-grade caps and resistors,
installing a new Oliver Archut / AMI Transformer, modding the
circuit according to Oliver's schematic, and using a new select
low-noise NOS Telefunken EC92 tube. Also includes a selected
Mullard-branded (Made in W. Germany) spare EC92 tube. Here is
your chance to get this great mic mod done without having to
wait for two year , as our turnaround time including burn-in
and testing is just 1-2 weeks!!!
"The top end retained
the soft, smooth nature, but improved the sense of space. Upper
mids remained even and clear, but the mids/lower mids (800-200hz)
got fuller but also really cleared up a lot !...this was the
biggest change i heard. The low end stayed rich and warm, but
tightened up a bit. Overall it made things fuller and more natural.
I was very concerned about messing with the sound i already like
with the 563's, this was more improvement than change. I am going
to mod both my CMV563s"

SOUND FILES:
Click below for MP3 sound files of the stock mic and after
mod. I think the difference is big enough that you can even hear
it from the MP3 files!!! The signal chain is a Presonus ADL 600
mic pre, through the Rosetta 200 A/D converters in to Logic on
an iMac. The Capusles used were a stock Neumann Gefell M55k omni,
and a new Thiersch
switchable M7/M8 transducer in the old Gefell M8 head.

DISCLAIMER:
This uses the Oliver Archut circuit mod and his AMI CMV563
transformer. While Oliver knows about our mod service and has
sold us his transformers, we are not accociated with him in any
other way, and he is neither endorsing or recommending us. We
have simply added this mod service in an attempt to cut down
the waiting time for this desirable upgrade, which can take up
to 2 years from some of today's backlogged mic tech's.
