AEA services and repairs vintage ribbon microphones, as well as our own line of ribbon microphones, preamps, and accessories. We’ve been servicing RCA ribbons since the 70s and have many spare parts for RCA 44, 77, and 74B type microphones in stock. We do not repair condenser microphones of any kind or other manufacturers’ electronics.

If you already know that you need to send in your microphone or preamp for repair or other service work, please download and carefully read our repair forms on the right side for details and instructions.
