Its major difference lies in its \u003cstrong\u003einterchangeable capsule head\u003c\/strong\u003e in the vintage U47 format: you can use compatible heads on the GA-47 Extended or even mount a Golden Age Project head on a vintage U47. Compared to a more \"classic\" GA-47, this architecture opens the door to a more modular approach, with a true logic of a high-end studio microphone designed to last.\u003c\/p\u003e\u003ch3\u003eWho Is It For and What Recording Applications?\u003c\/h3\u003e\u003cp\u003eThe GA-47 Extended is a tube large-diaphragm microphone targeting demanding studios and home studios wanting a sound signature inspired by major standards: \u003cstrong\u003evocals\u003c\/strong\u003e (pop, rap, song, voice-over), \u003cstrong\u003epiano\u003c\/strong\u003e, acoustic guitar, room, overheads, and all recordings where density, stable imaging, and harmonic texture typical of tube circuits are sought. Thanks to its polar patterns (cardioid, omni, and variable) and the -10 dB PAD, it can also adapt to more technical setups, from close miking to ambient placements.\u003c\/p\u003e\u003ch3\u003eHigh-End Studio Design: Interchangeable Capsule, NOS Tube, and Point-to-Point Electronics\u003c\/h3\u003e\u003ch4\u003eRemovable Capsule Head and Polar Patterns\u003c\/h4\u003e\u003cp\u003eThe GA-47 Extended incorporates vintage design details down to ergonomics: \u003cstrong\u003epolar pattern selector on the front face\u003c\/strong\u003e, under the grille, and \u003cstrong\u003eremovable capsule head\u003c\/strong\u003e. The standard GA-47 Extended HV head features a dual-sided capsule in \u003cstrong\u003eM7\/K47\u003c\/strong\u003e format (reference S47d) with a tone described as darker, very close to the character of the standard GA-47. For a brighter and more modern sound, a GA-47 Extended HM head with a \u003cstrong\u003eK67\u003c\/strong\u003e-type capsule (reference D35d) can also be chosen as the standard head, and the microphone can be supplied with both heads (optional depending on configuration).\u003c\/p\u003e\u003ch4\u003eCapsule Selection and Unit Consistency\u003c\/h4\u003e\u003cp\u003eTo ensure consistency from one microphone to another, capsule heads are produced with strict selection: about four times more capsules than needed are evaluated to retain only those meeting tight tolerances. The sensitivity difference between front and rear faces does not exceed 0.3 dB, and the difference between capsules does not exceed 0.5 dB, contributing to excellent reproducibility (valuable in stereo, multi-mic setups, and session recalls).\u003c\/p\u003e\u003ch4\u003eNOS Telefunken Tube and BV8-Inspired Output Transformer\u003c\/h4\u003e\u003cp\u003eThe circuit is based on a \u003cstrong\u003eNOS Telefunken 800 series\u003c\/strong\u003e tube, a very low-noise pentode connected in triode mode to reduce distortion and noise. This reference is described as a modern glass derivation of the VF14M associated with vintage U47s. The output transformer is a specially developed model: \u003cstrong\u003e6.5:1 dual bobbin transformer\u003c\/strong\u003e, designed as a replica of the \u003cstrong\u003eBV8\u003c\/strong\u003e, with a high-quality core to preserve bass, dynamics, and the \"size\" of the signal.\u003c\/p\u003e\u003ch4\u003eAudiophile Components, Wiring, and Optimized Power Supply\u003c\/h4\u003e\u003cp\u003eInside, the approach is decidedly \"old school\": \u003cstrong\u003epoint-to-point\u003c\/strong\u003e wiring with silver-plated copper wire insulated with Teflon, with the printed circuit board used only for ground connections. Solder joints are made with \u003cstrong\u003eMudorf Msolder Supreme SilverGold\u003c\/strong\u003e solder (Sn88, 6Cu, 1.8Ag, 9.5Au). The coupling capacitor is a \u003cstrong\u003eSOLEN\u003c\/strong\u003e (MKP, copper pins, made in France), complemented by low-loss \u003cstrong\u003eSIEMENS\u003c\/strong\u003e polystyrene capacitors and \u003cstrong\u003eALLEN BRADLEY\u003c\/strong\u003e carbon resistors, known for their warm sound reproduction.\u003c\/p\u003e\u003cp\u003eThe vintage-style power supply uses a low-noise \"R-style\" transformer with minimal stray field. Filtering includes a dual stage for the filament voltage, and the high voltage is filtered and stabilized via a Telefunken semiconductor zener diode. A \u003cstrong\u003eground lift\u003c\/strong\u003e switch is integrated to help resolve certain ground loop issues, and a \u003cstrong\u003e-10 dB PAD\u003c\/strong\u003e on the power supply allows confident work on very high SPL sources. Finally, the microphone cable is specially made (OFC copper, Teflon insulation, dense shielding) for clean and stable transmission.\u003c\/p\u003e\n\n\u003ch2\u003eTechnical specifications\u003c\/h2\u003e\n\u003cdiv style=\"display:flex;flex-wrap:wrap;gap:2rem\"\u003e\n\u003ctable style=\"flex:1 1 300px;width:100%\"\u003e\n  \u003ctr\u003e\u003ctd style=\"text-align:left\"\u003e\u003cstrong\u003eFrequency response\u003c\/strong\u003e\u003c\/td\u003e\u003ctd style=\"text-align:left\"\u003e20 Hz - 20 kHz\u003c\/td\u003e\u003c\/tr\u003e\n  \u003ctr\u003e\u003ctd style=\"text-align:left\"\u003e\u003cstrong\u003eCategory\u003c\/strong\u003e\u003c\/td\u003e\u003ctd style=\"text-align:left\"\u003estudio microphone\u003c\/td\u003e\u003c\/tr\u003e\n  \u003ctr\u003e\u003ctd style=\"text-align:left\"\u003e\u003cstrong\u003eDirectivity\u003c\/strong\u003e\u003c\/td\u003e\u003ctd style=\"text-align:left\"\u003eomnidirectional, cardioid\u003c\/td\u003e\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003ctable style=\"flex:1 1 300px;width:100%\"\u003e\n  \u003ctr\u003e\u003ctd style=\"text-align:left\"\u003e\u003cstrong\u003eCapsule\u003c\/strong\u003e\u003c\/td\u003e\u003ctd style=\"text-align:left\"\u003eLarge Diaphragm\u003c\/td\u003e\u003c\/tr\u003e\n  \u003ctr\u003e\u003ctd style=\"text-align:left\"\u003e\u003cstrong\u003eConnection\u003c\/strong\u003e\u003c\/td\u003e\u003ctd style=\"text-align:left\"\u003eXLR\u003c\/td\u003e\u003c\/tr\u003e\n  \u003ctr\u003e\u003ctd style=\"text-align:left\"\u003e\u003cstrong\u003eColor\u003c\/strong\u003e\u003c\/td\u003e\u003ctd style=\"text-align:left\"\u003eBeige\u003c\/td\u003e\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"display:flex;flex-wrap:wrap;gap:2rem\"\u003e\n\u003cdiv style=\"flex:1 1 300px\"\u003e\n\u003ctable style=\"width:100%\"\u003e\n  \u003ctr\u003e\u003ctd style=\"text-align:left\"\u003e\u003cstrong\u003eType\u003c\/strong\u003e\u003c\/td\u003e\u003ctd style=\"text-align:left\"\u003etube microphone\u003c\/td\u003e\u003c\/tr\u003e\n  \u003ctr\u003e\u003ctd style=\"text-align:left\"\u003e\u003cstrong\u003eTransducer\u003c\/strong\u003e\u003c\/td\u003e\u003ctd style=\"text-align:left\"\u003econdenser\u003c\/td\u003e\u003c\/tr\u003e\n  \u003ctr\u003e\u003ctd style=\"text-align:left\"\u003e\u003cstrong\u003eNumber of microphones\u003c\/strong\u003e\u003c\/td\u003e\u003ctd style=\"text-align:left\"\u003esingle microphone\u003c\/td\u003e\u003c\/tr\u003e\n  \u003ctr\u003e\u003ctd style=\"text-align:left\"\u003e\u003cstrong\u003eAnalog \/ digital\u003c\/strong\u003e\u003c\/td\u003e\u003ctd style=\"text-align:left\"\u003eanalog\u003c\/td\u003e\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003ctable style=\"width:100%\"\u003e\n  \u003ctr\u003e\u003ctd style=\"text-align:left\"\u003e\u003cstrong\u003eTube type\u003c\/strong\u003e\u003c\/td\u003e\u003ctd style=\"text-align:left\"\u003eNOS Telefunken 800\u003c\/td\u003e\u003c\/tr\u003e\n  \u003ctr\u003e\u003ctd style=\"text-align:left\"\u003e\u003cstrong\u003eInternal wiring\u003c\/strong\u003e\u003c\/td\u003e\u003ctd style=\"text-align:left\"\u003epoint-to-point silver-plated copper, Teflon insulation\u003c\/td\u003e\u003c\/tr\u003e\n  \u003ctr\u003e\u003ctd style=\"text-align:left\"\u003e\u003cstrong\u003ePrinted circuit board\u003c\/strong\u003e\u003c\/td\u003e\u003ctd style=\"text-align:left\"\u003eused only for ground connections\u003c\/td\u003e\u003c\/tr\u003e\n  \u003ctr\u003e\u003ctd style=\"text-align:left\"\u003e\u003cstrong\u003eSolder\u003c\/strong\u003e\u003c\/td\u003e\u003ctd style=\"text-align:left\"\u003eMudorf Msolder Supreme SilverGold (Sn88, 6Cu, 1.8Ag, 9.5Au)\u003c\/td\u003e\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003ctable style=\"width:100%\"\u003e\n  \u003ctr\u003e\u003ctd style=\"text-align:left\"\u003e\u003cstrong\u003eCapsule (standard head)\u003c\/strong\u003e\u003c\/td\u003e\u003ctd style=\"text-align:left\"\u003e34 mm, M7\/K47 \u0026quot;vintage style\u0026quot;
