  • The capsule is mounted on a 7 mm thick aluminium plate in a special way to minimize the effect from physical vibrations.
  • The sensitivity of the front and back side of the capsule do not differ more than 0,3 dB. The sensitivity between different capsules do not differ more than 0,5 dB.
  • The tight manufacturing tolerance will lead to a very good consistency between different GA-47 units.
  • The capsule is specially designed to complement the electronic circuit of the GA-47 to achieve a frequency response curve with a nice balance between the high, middle and low frequencies

 

MIC BODY AND GRILL

TUBE

OUTPUT TRANSFORMER

The mic body is made of brass, the grille is made of iron.

The GA-47 uses a NOS Telefunken 800 series super low noise pentode tube connected in triode mode in order to decrease distorsion and noise.

The GA-47 transformer is especially designed with a 6.5:1 dual bobbin transformer by a reputed transformer factory.

The grille, which is a critical component affecting the sound character, is similar to the one in the U47.

This tube is modern glass derivative of the VF14M used in the vintage U-47.

It is a replica of the BV8 transformer used in the vintage U47. It uses a high quality core material.

CAPACITORS AND RESISTORS

CAPSULE

The electronic circuit is built with point-to point wiring, all soldering points made with Mudorf Msolder Supreme silvergold solder.

The vintage style power supply PSU uses a high power R-style transformer with a low noise level and minimum stray field.

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.

The capsule for the GA-47 is designed to provide the requirements of modern day recordings.

All of the inside wire use pure silver wire and decrease the loss during the circuit transmission, also it can ensure the sound quality is transparent.

A simple but effective circuit uses dual-stage filtering for the filament voltage. The High voltage is also precisely filtered and stabilized using an ON semiconductor zener diode.

It is an axial capacitor made from MKP material with copper pins. It has a delicate, full sound and a wide frequency response.

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.

All components which are connected to electrical ground is connected to the ground plane on the circuit board.

The polar pattern switch is placed on the power supply so that the recording engineer can change the polar pattern between Cardioid and Omni remotely.

Other used capacitors are MIAL polystyrene film capacitors with very low loss.

Being a dual-sided one, it provides the GA-47 with both cardioid and omni polar patterns.

All other component connections use point to point wiring which results in virtually zero loss and crosstalk.

A ground lift switch will help to solve mains power related noise issues that can appear in some cases.

The resistors are ALLEN BRADLEY carbon film resistors made in the USA with vintage and warm sound.

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.
