Refurbishing Neumann U67's?
In 1964, I bought three Neumann U67s for use in my live recording
service, with which I made a bit of extra spending money when I was in college. Thanks to having a father in the import/export business, I was able to get someone in Germany to remove the Neumann badges, thereby allowing the mics to be imported without having to pass through Gotham Audio, which owned the rights to the Neumann trademark in the US at the time. The mics cost me $100 each (in 1964 dollars), which was far less than Gotham was charging. I have used them frequently over the years, most often for vocals. The singers with whom I work are used to the U67 sound. However, 43 years after my original purchase, all three are noisy, with various hisses and crackles. Additionally, the plastic sockets in mic side of the cable are cracked so that the setscrews no longer prevent the sockets from rotating inside their metal shell. Given these problems, I tossed in the towel and ordered a U87, which I presume can be made to sound close to the U67 on vocals because the capsules are ostensibly identical. The leaves the question of what to do about the U67s. I don't feel that I am qualified to work on them -- this is definitely work for a specialist. If they could be refurbished at a reasonable price, it seems to me that this would be worth doing. However, they are over 40 years old, and electronics of that era are difficult to keep in working order. I know that there is a certain amount of fetishism about the U67, but I would like to approach the decision in a more clear-eyed way. So my questions are these: 1. Is there anyone out there who is known to be reliable and to do good work in overhauling U67's? By this, I mean replacing or repairing components (including power supply capacitors) as necessary to achieve as close to "factory-new" performance as possible. 2. What is a reasonable price to pay for an overhaul? Thanks in advance for any advice. Bob Orban |

Doug Walker Microphone Repair in Canada. Should be easy to find on
line but if not get back to me and I'll dig up the contact info.

By this, I mean replacing or repairing Hi Bob - There is a world-known fellow out here in my neck of the woods (NW Oregon) whose first name is Klaus (originally from Germany) who can refurb/modify most of those older mics. The two major studios in town plus two independents have used him with excellent results for upgrades and repairs on both SD and LD Neumanns. Perhaps someone else will know exactly who I'm talking about and can provide current contact info; if not I have three, probably four, sources for references and for contact info. If no one comes up with the contact info do feel free to reply via email to this post directly and let me know; I can then get that for you. Best, Frank Stearns Mobile Audio -- |

first name is Klaus (originally from Germany) who can refurb/modify most of those older mics. Klaus Heyne. Doesn't have a website, you need to call him. Last I heard he was not taking any new orders until he caught up with a several year long backlog of work. Bill Bradley Mic Shop might be worth a call. Scott Fraser |

Dunno, a lot depends on what needs replacement. --scott -- "C'est un Nagra. C'est suisse, et tres, tres precis." |

I will contact them first. FWIW BLUE did some nice complete refurbishing of Vintage Neumann's U67's and Telefunken U47's, rechroming and the whole deal. Made them look great, but they have no website links for that kind of service anymore. Will Miho NY TV/Audio Post/Music/Live Sound Guy "The large print giveth and the small print taketh away..."

Refurbishing Neumann U67's?
Bob, the people who steered you to Neumann are correct--Neumann still
supports the U 67 completely (apart from the non-availability of the NU 67 power supply). They even did a complete reissue edition of the U 67 with all original parts at one point during the 1990s. They can normally supply anything that may be needed, including replacement capsules of the proper type. Those have never even been out of manufacture--the SM 69 and USM 69 stereo microphones use[d] the same exact capsule type, as does the present-day model U 87Ai. But it's not correct to assume that the U 87 is simply the solid-state counterpart of the U 67. The U 67's amplifier circuit uses a fairly complex feedback arrangement to tailor the capsule's rather bright "native" response, with 16 kHz sensitivity that is some 7 dB reduced relative to 1 kHz. The U 67 was introduced in 1960; by 1968, when the U 87 was introduced, it was considered desirable to make it just a little brighter and more incisive sounding. So the U 87's amplifier circuit has a different, simpler feedback arrangement, with response at the highest frequencies that is slightly more extended and elevated relative to that of the U 67. Thus the sound of the U 87 has never been quite as round and smooth as that of the U 67. --best regards |

Will, BLUE's refurbs were always very beautiful to look at, but they substituted BLUE's own capsules for the originals, and in some cases other important parts such as output transformers--even for microphones where the original parts were still functional and/or authentic Neumann replacement parts were readily available. This was certainly no secret. But any Neumann (or other) microphone refurbished by BLUE is definitely not going to sound like the original, and people should understand that clearly. What they did to microphones such as the U 47 or M 49 made them very difficult and expensive to restore to Neumann specifications and sound later on, if that's what a person really wanted. As you mentioned, though, they've since discontinued this service. --best regards |

They each made the mic sound very different.

Someone here as I recall (Ted maybe?) did a shootout of 3 different versions of U47 longbodies and prefered the BLUE restoration to originals (buying it from the Guitar Center in Westchester NY I mentioned had it on the shelf.) Also Mark Linett says he likes the BLUE version best too - and he has several U47's in his mic cabinet. Me, nearest thing I have to a U47 is my Soundelux U95S with the Blue capsule... Nice mic but somehow not quite as popular as it once was... Will Miho NY TV/Audio Post/Music/Live Sound Guy "The large print giveth and the small print taketh away..." Tom Waits |
