Ninety Ohm

Model One Desktop Headphone Amplifier

A single input desktop amplifier that drives headphones from 16 to 600 ohms without a gain switch, built on a through hole board inside a milled aluminium case. The volume control is a stepped attenuator with 24 positions, so the left and right channels stay matched at low listening levels instead of drifting apart the way a cheap potentiometer does.

02
The differenceEnclosures are cut from solid aluminium bar stock, not folded sheet, so the case is the heatsink
