รายละเอียดสินค้า |
The Linear845 combined tube amplifier, as a commemorative version celebrating the 25th anniversary of the establishment of Ober Audio, fully embodies Ober’s accumulation of R&D and manufacturing of electronic tube machines, and is currently the flagship product of the combined machine.
It adopts the class-A single-ended circuit with very beautiful sound in the tube amplifier, and the specially designed high-swing driver stage, which fully displays the guts of the 845 power tube "Dragons and Tigers". In particular, the input interface has two sets of true balanced inputs. The balanced signal is converted into the amplifying part through the famous Swedish LUNDAHL input transformer to meet the needs of most audio sources today. The power tube uses fixed bias technology, and the screen flow is manually adjustable through an intuitive meter to ensure that the tube is working in good condition. The user can also change the negative grid voltage of the final power tube through the switch in the machine and replace it with a 211 power tube. The machine's materials are uncompromising, RA resistance, EIZZ stepping potentiometer, Neutrick balanced input and output terminals and a series of high-quality components, supplemented by the scaffolding method of silver wire cross-linking and direct circuit connection in the machine. Provides high-quality internal electrical characteristics to ensure low loss of sound signals. With the good linear amplification ability of the electronic tube itself in the full frequency band without negative feedback, it greatly ensures the lossless, proportional amplification and high-speed signal response ability of the audio source signal. Provides a transparent, high transient auditory performance.
