This is the latest AR-51 model which now includes the TK51D capsule, a 34mm dual-membrane, edge-terminated design. This larger surface area provides an extended low end and a smoother, more open high end in comparision to the original TK67D. The implementation of this new capsule brings the AR-51 and AR-70 sonically closer to the ELA M 251E, C12 and C24 that employ the legendary edge-terminated CK12 capsule.

Currently in Stock: We have one brand new AR-51, as well as one open-box AR-51 that is in perfect condition and still has the full warranty. You can save an additional $200 by selecting the open-box AR-51 above.

For a Limited time, order a New Telefunken AR-51 from and receive a FREE BONUS GE 5-STAR NOS Triple Mica 6072A Tube which is the original tube that was included in the Vintage Elam 251 and a noticeable upgrade from the stock ECC81 tube. The GE 5-Star 6072A are getting hard to find and sell for as much as $250 per tube. It's yours FREE with the purchase of an AR-51, 251e, or C-12 only from!! That in addition to the stock ECC81 Tube also included with the AR51. We can install the GE 5 Star tube for you (upon request), or just include it as a spare tube. Either way you get both tubes at no additional cost to you!

While TELEFUNKEN Elektroakustik is well known for their historic recreation microphones, but as we all know those recreations are intended for the 'upper crust' of the recording industry who can afford the best of the best.

With this in mind they created the R-F-T Series of microphones as an affordable solution that delivers amazing tone, ultimate application flexibility at a price anyone who is serious about recording can afford.

The AR-51 is the culmination of this ideal. For the AR-51 they took the amplifier electronics of a C-12 and ELA M 251E and married them to an offshore capsule and power supply so they could bring the best of both worlds together for what are destined to become the classics of tomorrow.

While the capsule is built off shore, it is tested to very high tolerances for consistency in their Connecticut based US laboratory. The capsule is then coupled to a slightly tweezed classic amplifier. The core of this amplifier is NOS [New Old Stock] ECC81 vacuum tube which is coupled the same German built output transformer you will find in their far more expensive C-12 and ELA M 251E.

In use, the R-F-T AR-51 is a fantastic utility mic!! Its smooth mid-range, open top end, and solid well-balanced low frequency translation make it a great choice on anything from vocals to drums and percussion to acoustic guitar to saxophone. There are 1000 more uses, but we think you get the idea that this is indeed a remarkably versatile microphone.

The remote pattern selector (located on the power supply) provides 9 different polar patterns, giving the user a myriad of choices for how to record the source sound in a manner that will best compliment their production.
