Ribbon Microphone Repairs

The Xaudia microphone repair service can bring your old ribbon mic back to life. We can install a new ribbon, check and rejuvenate the magnets, and upgrade the transformer. We are based in the UK, giving owners in Europe an alternative to sending their ribbon microphone to the USA.

Each microphone we service is examined on receipt, and before we start work we provide an estimate of what needs doing, how long it will take and how much it will cost. Rates start from around £40 plus postage*, depending on the type and condition of your microphone. 

(*Typical price for a good condition Reslo microphone. Please ask about your microphone).

Ribbons

In many cases a new ribbon will give lower noise, higher output and extended frequency response. We use precision cutting and corrugating equipment based on the original methods used by RCA, to ensure the best possible replacement ribbon for your treasured ribbon microphone.

Transformers

Output transformers can become broken or damaged, and we have coil winding facilities to rewind and repair vintage output transformers. Although many vintage transformers are excellent, some others are not, and some modern budget ribbon mics have particularly weak transformers.

We supply and fit replacement output transformers to both vintage and modern microphones, and use transformers made by Xaudia and SAMAR. The SAMARs are a toroidal design with extremely low DC resistance, which gives the lowest possible noise floor. We can also create a custom output transformer to your requirements.

Magnet Upgrades

In a ribbon microphone the output level is proportional to the magnetic field strength. Old ferromagnets can lose their strength over time, leading to weak output and a noisy microphone. We can measure your magnetic field and replace or boost the magnets for many microphones.

We can repair most vintage ribbon microphones, including Altec, B&O, Cadenza, Electrovoice, EMI, Grampian, GEC, Grundig, HMV, Lustraphone, Melodium, Oktava, Reslo, RDC, RCA, STC, Tannoy, Trix, Western Electric, and many others.  Please ask if your microphone is not listed.

And of course, we can repair and upgrade modern mics too, such as T-Bone, Nady, Stellar and so on.
