Vintage and Coles Microphone Repairs

AEA services and repairs vintage and Coles ribbon microphones. Our standard policy is to restore microphones as close as possible to their original operating specifications. Because time and countless sessions can take their toll, some owners also desire cosmetic repairs or full restorations to enhance the value of the microphone. A “new-looking” microphone can also inspire the artist who works with it. See below for full list of microphones AEA repairs. Due to high demand, we currently have to quote six to eight weeks for vintage microphone repairs.

Repair Order Number

Each Vintage and Coles Product Repair is issued a Repair Order Number. You will receive this number in the confirmation e-mail of your repair. Please include your name and Repair Order Number inside or on the repair package.

If you do not receive the confirmation message within a few minutes of filling the form, please check your Spam or Bulk E-Mail folder just in case the confirmation email got delivered there instead of your inbox.
