AREN'T YOU THE GUYS THAT FIX NEUMANN MICROPHONES ?
Gotham Gazette

Gotham Audio LLC receives many inquiries regarding the repair of Neumann microphones. From 1958 through the early 1990’s, the Gotham Audio Corporation was the exclusive US distributor for Neumann mics.

After Gotham stopped selling the microphones, they continued as an authorized service center. Throughout the 1990’s these repairs were performed by Gotham Service Lab, headed by Joe Leung. Joe retired some 15 years ago and the Gotham Service Lab is no more.

We have enjoyed corresponding with a number of talented master craftsmen who are involved with the repair and modification of precision electronics, vintage gear, and specialized or boutique electronic design. We are privileged to have them as both GOTHAM clients and resellers. We’ve listed a few below who may be particularly useful to those seeking repair and/or modificatio of vintage Neumann microphones:

Much of Joe Leung’s shop equipment was sold to Tracy Korby, microphone builder and modifier, who began his career with Stephen Paul Audio, at one time, the only US service center outside of Gotham authorized to do warranty work for Neumann. Over the years, many have used Korby Audio Technologies as a source for repairs and service for Neumann microphones, but at this time we must advise due caution in dealing with them

Tracy’s business has relocated quite a few times over the years, moving from the West Coast to Pennsylvania, then to the Blackbird studio complex in Nashville, then to Georgia and more recently to Virginia and then back to Nashville in 2014. Our communications with Korby since December 2013, have created doubts as to their ability, at this time, to conduct the repair business in an orderly and professional manner. We advise similar caution in dealing with another former Stephen Paul technician, Tony Merrill.

The original Gotham Audio Corporation and the associated Gotham Service labs have both closed their doors many years ago. Gotham AG in Switzerland and Gotham Audio LLC in the US continue the Gotham tradition but we are only involved with the sale of Gotham Audio Cable.

We greatly appreciate Gotham’s historic ties with companies such Neumann and EMT and we attempt to research and document that history so as to preserve a very special piece of audio history. But here in the US we are not involved with the sale, repair, maintenance, appraisal, documentation, etc. of any professional audio equipment from the old Gotham catalog.

If you have a recognized and professional business involved with the repair, restoration and modification of vintage Neumann microphones, then we’d love to hear from you.

Finally, although this has noting to do with Neumann, we wanted to give some special recognition to Clarence Kane at ENAK MIC REPAIR in Pittman New Jersey, a city forever identified with the legendary RCA electronics. Many owners of vintage ribbon microphones would agree that Clarence’s shop should be declared a National Historic site. He has been, and still remains, an invaluable resource to all who view ribbon microphones, especially the RCA models, as both historical treasures and a continuing vital component in recording and broadcast equipment inventories.
