The Linear 845 tube integrated amplifier is a 25th anniversary edition and flagship of the integrated amplifier line.
Linear 845 is Class A single-ended tube integrated amplifier. Specially designed high swing drive stage that maximizes the dynamics of the 845 power tube.
It is particularly worth mentioning that it has two sets of true balanced inputs, and the balanced signal is converted to a single-ended by the Swedish LUNDAHL input transformer and then amplified to accommodate the needs of most of today’s audio sources.
The intuitive meter head can be manually adjusted to bias the 845 power tube to ensure optimal operation. The user can also replace the power tube 845 with 211 through the switch inside the machine.
The machine’s materials are uncompromising, RA resistors, EIZZ step potentiometers and other high-quality components, Point to point welding to ensure the lowest loss of sound signals.
