Page 5: Introduction
The frequency range and output resistant limitations of classic tube designs are evident as soon as you connect the amplifiers. These designs often only perform to their full potential when they are used with special loudspeakers. OCTAVE amplification and power supply technology has largely overcome these well- known problems. -
Page 6: Jubilee Mono Ultimate Product Description
This is a path no one can take quite as Octave can, because we have been developing and manufacturing bespoke transformers ourselves using our own proprietary technologies for decades. - Page 7 1. INTRODUCTION By any measure, the JUBILEE MONO ULTIMATE achieves a beauty of sound reproduction that is in no way inferior to the sound of a single-ended power amplifier, but without the inherent limits such designs impose. With the Octave JUBILEE MONO ULTIMATE, one will experience music as it should be - intense, emotional, and unforgettable.

3. GETTING STARTED 3.5. Recommended starting procedure Please note: Before you use your amplifier for the first time, we strongly recommend you to follow the procedure described in the following nine points, even if your dealer has already set the amplifier up for you. By checking these nine points, you will also familiarize yourself ... - Page 13 3. GETTING STARTED Functional test, muting If all values are correct, you can check the “Muting” function. When the muting function is active, not only the inputs are short-circuited to allow signal cables to be connected; the current to the power tubes is also reduced to nearly 0. Checking the bias of the tubes while the muting function is ON, the reading of the display shows the value less than 50 of all tubes.

Page 19: How The Bias Works
This is why we have incorporated a bias measurement facility into the JUBILEE MONO ULTIMATE mono blocs that allows you to set the bias yourself without the need for test equipment. The protective cover does not have to be removed to do this. -
Page 20: The Electronic Protection System
5.2. Electronic Protection System The JUBILEE MONO ULTIMATE features a comprehensive electronic monitoring and protection system. This system will automatically switch off the JUBILEE MONO ULTIMATE in case of a fault occurring in the power section. The protection system has been designed to keep the unit safe from the consequences of overloads of any kind and to protect the output tubes from current surges. -
Page 21: Power Pre Selector
After approximately 8 - 10 minutes without receiving signal the Ecomode is turning down the power of the Tube Output stage. In this “sleep” mode, the JUBILEE MONO ULTIMATE draws less than 80 W power compared to approx. 400 W in normal operation mode (in case of BIAS High). -

Driver tubes normally do not require periodical replacement. Operating the amplifier without the side panel is dangerous and not recommended! Tubes should only be replaced by qualified personnel. -
Page 25: Troubleshooting
7. TROUBLESHOOTING 7.1. In general Noise and hum Hum in an audio system is often caused by several system components being grounded separately. It is particularly common in systems containing tuners, VCRs or satellite receivers connected to an aerial, where a hum loop may be introduced via the aerial input. Although the JUBILEE MONO ULTIMATE is also grounded, it is equipped with a special technology that reliably prevents ground loops. -
Page 26: Identifying Defective Tubes
7. TROUBLESHOOTING 7.2. Identifying defective tubes There are especially five reasons why tubes can become defective. 1. You should remove any tube that fails to provide a stable reading after an initial warm up period. Any tube that reads 0 is defective and non-functional and must be replaced. Tubes showing a reading of 0 cannot be corrected by turning up the bias control. -

10. FAQ Can you operate the amplifier when no loudspeakers are connected? Yes. All OCTAVE amplifiers are protected against open circuit conditions, i.e. they will not be damaged if operated with the loudspeakers disconnected. However, when connecting your loudspeakers to the amplifier, you should set the volume control on your preamp to 0 to avoid excessive output to the speakers. - Page 32 We reserve the right to alter and improve the specifications in pursuit of better.
