Golden Age GA-251 Tube Microphone
The Golden Age GA-251 Tube Microphone is inspired by a truly classic mic model. The Telefunken ELA M 250/251 was made for Telefunken by AKG after Neumann discontinued its OEM production of the Telefunken U-47.
The Golden Age GA-251 shares the same design goal that was set for the GA-47: to offer the classic qualities and advantages that a vintage unit in perfect condition would provide and doing so at a very low price point.
Mic body and grille
The mic body is made of brass, the grille is made of iron. The grille, which is a critical component affecting the sound character, is similar to the one in the 251.
The GA-251 uses a 34 mm K251 style capsule. Being a dual-sided one, it provides both cardioid and omni polar patterns. In order to get a good consistency between units, for each production run of 50 pcs GA-251 units, approximately 200 capsules is evaluated in order to find 50 capsules with specifications that lie within the tight tolerances.
The GA-251 uses a NOS Phillip 5480W super low noise pentode tube connected in triode mode in order to decrease the noise.
The GA-251 transformer is specially designed with a 10:1 AMI style dual bobbin transformer. It is made from permalloy steel sheet from USA and enamelled wire from Germany. It offers a wonderful sound character with a high resolution and great balance between the low, middle and high frequency bands.
Capacitors and resistors
The coupling capacitor is made by Solen from France. It is a high balanced film capacitor made from MKP material with pure oxygen-free copper connections. It has a very delicate and balanced sound.
The electronic circuit is built with point-to point wiring, All soldering points made with Mudorf Msolder Supreme solder.
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 minimum stray field.
The cable is specially produced using 99,99% pure oxygen-free copper, Teflon insulation, tin foil and 98% kitmesh, ie with a very high braided density of the cable shield. It has a very open and smooth sound. The mic connector is an aviation style plug providing solid connections and a long life.
