Octave Audio

The Octave Jubilee preamp optimally combines the properties of lamps and transistors. In the input stages, where it is important to obtain maximum gain with the least noise, double ECC83 triodes operate, and powerful transistors are installed behind them, allowing for low output resistance and good load characteristics.

The special version of the Octave HP 700 SE tube preamp is based on the classic 1986 Octave HP 500 circuit design, and the modular design makes the device flexible, allowing it to adapt its functionality to the needs of the owner.

The Octave HP 300 SE is an improved version of the HP 300 MKII. The new device is more versatile in terms of switching, has some improvements in the output stage and has an external power supply, which helps isolate its sensitive circuits from noise and interference from the power grid. It is possible to stepwise change the gain (three options are available), which makes it possible to precisely match the Octave HP 300 SE with the terminal amplifier and speaker.

The Octave Phono Module Tube Preamp (IN 2 + IN 6 + OUT 2) is a version of the basic model with two MC phono corrector input modules and one output module with fixed and adjustable RCA connectors. In fact, this device has on board everything you need to work with vinyl turntables equipped with MC cartridges.
