Hello Eric,
in my original question, can Neumann reissue... I already pointed out maybe not the U47, but for certain the M49/50 and U67/M269 as tube mics. The KM series is possible as well. The U47 would be possible if the is a financial back bone to overcome all the difficulties of the VF14 design, custom metal, etc.
I agree that there is no bad mic, there is only a wrong application, and that a good engineer can make even a inferior mic sound good. But aside the use for acoustical unchallenging situations, let say as an speakermic like the one you can currently find on David Letterman's desk, the M147 has no use and flair to a good working U47. Not even a basic relation, and believe me I bought a M149, a M147 after they were introduced but none of the mics came ever as close than the vintage counterparts, nor the sparkle that Neumann mics were famous for.
Please do not get me wrong, I am a big Neumann and Sennheiser fan.
I recently talked with Mr. Vogt the last living member of the M49/50 design team (just as an side note Neumann DID NOT develop it), there would be a possibility making the MCS2 or even the AC701 in a small hand made production version. Just to give you an idea, the first 15000 AC701 were handmade, and several of the people that made the last AC701 in 1978/79 are still around.
It is not the problem that it can not be done, the problem is they do not want to do it. Why? My speculation is that they don't know how!
The U67 could be done quite easy, without any effort, there are sufficient amounts of EF86 tubes on the market, there are several kilos of the original transformer lamination available...
The last time they issued the U67 was done with NOS parts, but that was nearly 10 years ago.
Over the next few year something will happened, there are several great mic manufacture today, none hit it like the historic ones, but if Neumann will not do it, somebody will step up to the plate and hit a homerun!
By the way, Gefell is one of the two manufactures that make incredible capsules, but do not compare the UM92 to a U47 or M49 due to so may differences in mechanical and electronic design.
If you get rid of the choking components, the UM92 is in the same battle class than the other M7 based mics, like M49 and U47...
Will coment on J.J. coment later...
