\nBy disassembling a C800G and handing it\u00b4s 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.<\/p>\n
\nIn order to ensure the tube will have a long life, we are using a NOS GIFTE 6AU6 tube from France, it has a maximum anode voltage rating of about 300V. The tube in this circuit has an anode voltage of 90V and will generate more heat than tubes in many other tube microphones that typically uses voltages between 35-50V. The higher voltage used in the GA-800G increases the heat dissipation so the semiconductor active cooling system is an important element in the design.<\/p>\n
\nThe classic 800G uses two 6AU6 tubes as rectifiers for the high voltage rail, they work as pseudo diodes by connecting all grids to the anode that outputs about 290V.
\nAfter a lot of listening tests comparing a tube rectifying circuit with a solid state one, we found that we did prefer the sound of the latter so this is what we decided to use. The additional advantage is that there is no need to worry about replacing tubes in the power supply.<\/p>\n
\nThe metal resistors and electrolytic capacitor from Japan are of special audiophile audio types. The coupling capacitors are Siemens EPCOS from Germany.
\nThe connecting wires inside the GA-800G are oxygen-free copper wires from Japan. The solder is FELDER silver\/copper-containing solder from Germany.<\/p>\n
