TELEFUNKEN Elektroakustik (and its Vintage Tones counterpart) offer full repair and restoration services specializing in new and historic vacuum tube based microphone systems.
Should your new or old microphone system need factory service, you will be assigned an RMA (Return Merchandise Authorization) number specific to your repair.
To request an RMA form for your microphone system, please fill out the form here.
After you have submitted your RMA form, you will be emailed your RMA number from our lab technicians. You will be required to print and include your RMA form in the shipment of the microphone system to our repair lab.
Please be sure that you have included all the accessories necessary for repair. For tube microphones, the POWER SUPPLY AND CABLE ARE REQUIRED TO PERFORM REPAIRS.
Also, it is important to write the assigned RMA number on the outside of the shipping box before sending it to the assigned authorized service center.
Repairs on newly manufactured TELEFUNKEN Elektroakustik microphones are covered under a limited warranty plan and repair costs will be determined based upon the date of purchase and the date in which the warranty was registered. Repairs & Service covered under the warranty plan are done at no charge for labor, parts and service. We simply ask that you obtain an RMA number and cover the cost of shipping to our lab. TELEFUNKEN will cover the cost of GROUND or INTERNATIONAL ECONOMIC shipping back to you. Expedited shipping can be accommodated for, however, the customer is responsible for paying the additional shipping fees beyond the cost of ground shipment. The address for our laboratory is as follows:
300 Pleasant Valley Road, Suite E
South Windsor, CT, 06074
*Please note, vacuum tubes are covered under a 90 day warranty plan. Should your vacuum tube go bad AFTER 90 days, but before the registered warranty plan on the other microphone parts and labor expires, you will only be required to cover the cost of the new vacuum tube. Labor and return shipping will be covered under the warranty plan.
Should your vacuum tube microphone need service or repair beyond the factory warranty plan, there will be a $65 evaluation fee per mic system (Diamond Series, R-F-T Series and vintage tube mics systems). All work performed on your microphone system will be done at an hourly rate of $125 per hour, plus the cost of parts and return shipping. The $65 evaluation fee may be applied towards the first hour of service.
