The Linear845 integrated tube amplifier is a 25th anniversary edition celebrating Opera Audio’s 25 years in business, drawing on extensive experience and years of technological achievements in the manufacturing and development of tube amplifiers. It is the flagship model among integrated amplifiers.

The Linear 845 is a Class A single-ended integrated tube amplifier. It features a specially designed high-swing driver stage that maximizes the dynamics of the 845 power tube.

Particularly noteworthy is that it features two sets of true balanced inputs, where the balanced signal is converted into a single-ended signal by the Swedish LUNDAHL input transformer and then amplified to meet the requirements of most of today's audio sources.

The intuitive meter can be manually adjusted to optimally set the bias of the 845 power tube and ensure perfect operation. The user can also replace the 845 power tube with a 211 tube and switch between them using the switch inside the amplifier.

The machine's materials are uncompromising, featuring RA resistors, EIZZ stepped potentiometers, and other high-quality components, with point-to-point wiring to ensure the lowest loss of audio signals.
