The Golden Age Project GA-800G is a large-diaphragm tube condenser microphone
The Golden Age Premier GA-800G is currently the only microphone to fully reproduce the C800G. It´s appearance and structure, as well as accessories and circuit principles, including its sound character, strictly follows the original design. All of the parts including the power plug and the pin definition of the power supply are the same as in the original C800G.
The classic C800G is the only tube microphone in the world equipped with a semiconductor active cooling system that results in a higher signal-to-noise ratio compared to most other tube microphones. It has a very high-quality modern sound performance.
Even though its based on the original, the circuit board has been upgraded to a ROGERS ceramic circuit board that has superior insulation parameters and offers a more stable performance. The coupling and bypass capacitors has also been upgraded, resulting in a deeper and more exact low frequency performance and a more delicate and transparent high frequency reproduction.
The classic semiconductor active cooling and external cooling system from the C800G is also used in the GA-800G. This is to ensure that the GA-800G has the highest possible signal-to-noise ratio. The tube (a 6AU6) is mounted in an aluminum casing, with the semiconductor cooling chip being attached to the bottom of the case. The temperature of the tube in the GA-800G is the effectively kept down when the GA-800G is in it´s working state, the heat generated by the tube is actively dissipated. The heat that the tube generates is transferred to the reverse side of the semiconductor and transferred to the effective outer aluminum alloy heat sink at the rear of the microphone. This heat sink will then dissipate the heat from semiconductor cooling chip to the air surrounding the GA-800G.
PCB BOARD
A ROGERS ceramic gold-plated circuit board is used. This type of circuit board is usually used in high-end aerospace communication products, the cost is about twenty (20!) times higher than an ordinary PCB board.
CAPSULE
By disassembling a C800G and handing it´s capsule to a manufacturer with more than twenty years of microphone capsule production experience, they were able to produce a capsule that matched the characteristics of the original one. The capsule used in the GA-800G can handle a higher sound pressure level than the original one and it has almost the same sound character.
TUBE
In order to ensure the tube will have a long life, the GA-800G employs an NOS GIFTE 6AU6 tube from France. The tube uses an anode voltage of 230V and will generate more heat than tubes in many other tube microphones, so the semiconductor active cooling system is an important element in the design.
CAPACITORS, RESISTORS AND SOLDER
The metal resistors and electrolytic capacitor from Japan are of special audiophile audio types. The coupling capacitors are Siemens EPCOS from Germany. The connecting wires inside the GA-800G are oxygen-free copper wires from Japan. The solder is FELDER silver/copper-containing solder from Germany.
