Essential Two-Chassis Line Preamp
A tube line preamplifier with its power supply in a separate chassis, for a quieter background.
This is the Essential Line Preamplifier built the way we build our flagship preamps: the power supply lives in its own chassis, connected by one cable. Moving the power transformer and rectifier away from the audio circuit lowers hum and makes the background noticeably blacker, especially with sensitive speakers. Transformers are wound in Thailand to our design, and the chassis sits in a wood frame.
