How do I find out about the status of my repair?

Please contact us at repairs@ribbonmics.com or call (800) 798-9127 and ask for the Service Department.

We quote six to eight weeks for microphone repairs. Rush jobs for functional studio repairs (i.e. re-ribboning, new cables) can be accommodated in two weeks for an additional charge of $100 per mic. Restoration and cosmetic work repairs cannot be rushed.

What is the turn-around time for vintage microphone repairs?

Due to high demand, we currently have to quote six to eight weeks for vintage microphone repairs. 

Rush jobs for functional studio repairs for vintage mics (i.e. re-ribboning, new cables) can be accommodated in two weeks for an additional charge of $100 per mic. Restoration and cosmetic work repairs cannot be rushed.


How much does a re-ribbon cost?

Putting a new ribbon into all AEA microphones and most vintage RCA microphones currently cost $165.00 USD. Re-ribboning Coles/STC 4038 and 4104 currently costs $197.00 USD, because we have to import replacement ribbons from Coles. All prices are subject to change. Please have a look at the Vintage and Coles Microphone Repair Form for additional information and shipping instructions. Please note that for all non-warranty work, at the time the repair order is placed we require a valid credit card to secure the order prior to beginning the work on your microphone. The credit card will not be charged until the job is complete.
