Brand Name: Warm Audio

Model Number: WA-47jr FET


The WA-47jr FET offers one of the most coveted classic microphone capsule designs in an affordable microphone circuit. The WA-47jr FET uses a high quality discrete transformerless circuit with Toshiba FET's, Wima film capacitors, and Panasonic electrolytic capacitors. The WA-47jr FET brings the tone and character of the classic '47 style microphone to you through the most critical component (its capsule) and is able to maintain an aggressive price-point by simplifying the rest of the circuit topology. The WA-47jr FET's simplified circuit is in no way a low quality circuit but is simpler to build and uses less components than a vintage tube microphone, which allows us to offer it at such a bargain price. The WA-47jr FET uses the same capsule as the Warm Audio flagship WA-47 tube microphone and sounds wildly similar to the WA-47.
