How do we do it?

We have 70 years of combined experience in the service and repair of vintage and new Neumann microphones.  We carefully disassemble them, painstakingly clean them, troubleshoot the electronics, replace faulty and malfunctioning electronic and mechanical parts with original Neumann parts wherever possible, put them back together with love, and get them back in your hands, as good (or BETTER) than new.

Microphone Repair wants to take this opportunity to officially welcome and introduce you to Cody Brown, the newest member of our Technical Staff


We troublshoot down to component level!

The Microphones

The most highly valued microphones are a mixture of new and vintage equipment. Here are  4 typical high quality microphones from Neumann and Telefunken. These are the Bugati’s and the Lamborghinis of the recording world and we bring them back to life!

Vintage Neumann U47

These vintage microphones have aged well. This is A USED Microphone that comes with a hefty price tag. Why? Because you need the best. And if it breaks in the middle of a session, we know what to do.

Vintage Neumann U67 Tube Condenser

These Tube Condenser Michrophones are highly prized. A microphone like this is valued at $10,000 to $15,000 Will it cost that much to make it sound like new? No, but it will be well worth the cost of repair and refurbishment.

Vintage Telefunken U47 Tube

Some of these Tube Microphones are the most expensive in the world. They were made 50-70 years ago. They don't make them like this anymore. But yes, if you have one that's not working, we can fix it!

Telefunken Elektroakustik ELA M 251E

This Telefunken is a replica of a microphone from the 40s and ’50s with legendary performance and longevity. But they do wear out eventually. The circuitry and technology don't last forever. But if it's not working, we'll fix it

I would suggest you use David to anyone looking for Microphone repair. Amazing price. Thanks David!

I want to thank you so much for such a pristine job you did on fixing my Soundelux 251. I will certainly recommend your expertise to others and will definitely be sending all my future work your way. The mic is sounding better than ever!

Also, I really appreciate your flexibility with turn-around time. Thanks to your great workmanship and punctuality my project is back on track with hardly any down time.

Thank you again.

Mr. Brown,

I want to wish you a Happy New Year. I just gave your info last week to someone I know that needs some work done on his Neumann.

The mic you repaired for me is a blessing. I use it each and every day. I hope to see you soon. Thanks Again

David is an incredible tech! In the past I have trusted him with my vintage Tele 251, M49 & U47. Very happy to have him looking after my babies. David also has a great attitude which goes a long way when it comes to dealing with high end vintage microphones that need some love. 5 STARS! 

The Humble House Music Studio

I live in the Bay Area and had been looking for a great microphone repair connection as I was having some problems with my km184s. David was recommended to me by several studio engineers. I’m so glad to have learned about David. Super fast turn around time, and he even took the time to call me to make sure he addressed all the issues. Microphones came back repaired and working better than ever. I would highly recommend David for any microphone repair.

I have used and refer many of my clients to David for their microphone repair.

David Brown is the only guy I trust with my microphone repair, David is a great communicator and Orbit Audio (my studio in Seattle) have used him for years now. 100% trustworthy and delivers on time, which is a rare thing these days.

Thanks a million for taking care my most prized procession, the vintage Neumann U67 I inherited from my dad. After years of sitting in storage, plus decades of being talked into by chain-smoking DJs/newscasters at my dad’s radio station, the mic had accumulated layers of gunk.

You lovingly brought this old classic mic back to life and made it sound like what it is, a world-class performer. It’s your personal service, easy communication, plus obvious passion you have for your work that makes you very easy to recommend.

If this review manages to land you a crapload of new clients, then I feel I’ve done all those people a favor.

Thanks a million!

Joe Wilmot

I’m from Vancouver Canada and I sent Dave my Neumann M147 tube microphone. I’m usually hesitant to trust other people with my equipment, but with Dave he provided great service, communication and a quick turnover rate. Not to mention my mic sounds amazing!!!

Thanks Dave!

I’ll be sending you all my problems… haha.
