Golden Age GA-47 Tube Microphone

The Golden Age GA-47 Tube Microphone has been born from a lot of hard work and real world testing. The end result is a microphone with a very sweet character that should appeal to a great number of users and a microphone that can be used for the most demanding recording tasks.

The Golden Age GA-47 Tube Microphone has proved itself to be a great all-rounder, this is not a “vocal-only” microphone. The Golden Age GA-47 is not a product that will be built in huge quantities on a big assembly line. It´s a product that is built by hand, fifty units at a time in a small workshop by a skilled and dedicated staff. It uses very high quality components all the way to achieve the desired goal, allowing me to answer “yes!” to the rephrased question mentioned above.

Mic Body and grill
The mic body of the Golden Age GA-47is made of brass and the grille is made of iron. The grille, which is a critical component affecting the sound character, is similar to the one in the U47.

Capsule
The capsule for the Golden Age GA-47 is designed to provide the requirements of modern day recordings by mixing the character between a vintage K47 capsule and the one from a K67-style capsule with a wide frequency response and high sensitivity. The result is a truly great sound. Being a dual-sided one, it provides the Golden Age GA-47 with both cardioid and omni polar patterns. In order to get a good consistency between units, for each production run of 50 pcs GA-47 units, approximately 200 capsules is evaluated in order to find 50 capsules with specifications that lie within the tight tolerances.

Tube
The Golden Age GA-47 uses a NOS Telefunken 800 series super low noise pentode tube connected in triode mode in order to decrease distorsion and noise. This tube is modern glass derivative of the VF14M used in the vintage U-47.

Output transformer
The Golden Age GA-47 transformer is especially designed with a 6.5:1 dual bobbin transformer by a reputed transformer factory. It is a replica of the BV8 transformer used in the vintage U47. It uses a high quality core material.

Capacitors and resistors
The coupling capacitor is made in United Kingdom, the brand is Ciarit, the same type used in the famous and very expensive B&W Nautilus loudspeaker. It is an axial capacitor made from MKP material with copper pins.It has a delicate, full sound and a wide frequency response. Other used capacitors are MIAL polystyrene film capacitors with very low loss. The resistors are ALLEN BRADLEY carbon film resistors made in the USA with vintage and warm sound.

Power supply transformer and electrolytic capacitors
The vintage style power supply PSU uses a high power R-style transformer with a low noise level and a minimal stray field. The electrolytic capacitors are of a high quality audio style type. A simple but effective circuit uses dual-stage filtering for the filament voltage. The high voltage is precisely filtered and stabilized using an ON semiconductor zener diode.
