The Coffman Labs G1-A is a limited production amplifier that has taken three years to come to fruition, indeed it is the only product in the company’s arsenal. Featuring rare and custom parts the G1-A been designed in Portland, Oregon as something that will last for decades with proper care. It is a line stage, phono preamplifier and a headphone amplifier.

In part the G1-A  has been inspired by an RCA amplifier around a century old. As with the RCA amplifier the G1-A is said to contain  “nothing that could degrade easily over time”.  All internal wiring is point-to-point and is hand done, though apart from the input and output wire runs are non-existent due to the 3D topology of the layout.  All of the components are claimed to be “over-sized for voltage” and all switches are “military aircraft quality and rated for millions of operations.”

The Coffman Labs preamplifier is available in 120 or 24 volt versions, has a separate power supply and has a tube compliment of 2 x 12AX7 for RIAA, 2 x 12AU7 for phono boost, 2 x 5687 in the line output and a single 5ARE.

The Coffman Labs G1-A is being sold in the US exclusively through Echo Audio from June 2012 at a cost of 5500$
