The Pearlman TM-47 microphone is based on the venerable U47 and is built in a body reminiscent of the classic look of the 50s and 60s. The stock TM-47 is a cardioid microphone made with the Pearlman K47 style capsule (made in Southern California), a 6SJ7 or 6AC7 (EF14 or EF12 available on request) tube, hand wired, point-to-point circuit with paper-in-oil output capacitor, and the Pearlman BV8 type output transformer. All Pearlman microphones come with shock mount, Mogami cable with Neutrik connectors, USA made power supply, and aluminum carrying case.
