INTRODUCTION

AN INTRODUCTION OF MAVIS TUBE MOSFET TRANSFORMER

MAVIS’s Tube Mosfet Transformer is a hybrid tube amplification product line
designed Single-Ended Class A for input and driver stage,
using Mosfet and Output Transformer for power stage.

The hybrid tube amplification includes Master Series and Reference Series.

MAVIS’s hybrid tube amplification exploits the emotional sound of the tube and the high power of solid state amplification. This design achieves both wonderful sound quality and an ability of well controlling all frequencies. Therefore, MAVIS’s hybrid tube amplification is extremely a good choice for reproducing all genres of music as correct and natural as possible as well as a great companion for all Hi Fi and High End loudspeakers. Also, with its flexibility and multi-functionality, MAVIS’s hybrid tube amplification brings an outstanding convenience in connecting and combining with many types of player including both analog devices and streamers. This brings to the user a diversity of playing with many types of high resolution music sources.

DESIGN MINDSET

After a long journey in researching and developing various tube amplification designs from 2006 until today, our target in New Generation hybrid tube amplification design is taking advantage of great achievements of tube amplification designs researched and developed by our R&D team. Accordingly, all engineering applications and combinations of tubes and components are optimized to get the best sound that we define as natural, correct and emotional sound reproduction.

– Zero Feedback

Our designers have seen that many designs of hybrid amplification today are popular with a combination of a tube pre-amplifier and solid stage power amplifier with many amplification stages. This design solution usually uses too much feedback, which reduces the natural and detail of the original sound, making the reproduced sound become hard, dry and less emotional. Using too much feedback for the amplification has more negative results than its benefit for the sound reproduction. Therefore, in the MAVIS’s Master Series hybrid tube amplifiers, we limit maximum feedback in amplifying to achieve the most natural and correct sound.

Indeed, Zero Feedback is one top of our criteria when designing amplifiers. This engineering method preserves the naturalness of the sound, so that the music is conveyed most faithfully and emotionally.

– Using Output Transformer and Interstage Transformer in hybrid tube amplification

Output Transformer (OPT) and Interstage Transformer (IT) are always known as a very high cost component that is often used in high end tube amplifiers. This component is also the best choice in tube amplification design to get the most natural and high fidelity sound quality. In the world at present time, the MAVIS’s Tube Mosfet Transformer amplifiers are the unique hybrid tube amplifiers using both OPT and IT. Our technology of OPT and IT has been researched and developed for many years since 2008 until now and these are the very important components that contribute to the best sound quality of our all tube amplifier and hybrid tube amplifier today. Our OPT and IT are made in-house by the highly skilled technicians.

– Assembling the hybrid tube amplifier by Point-to-Point method

Point-to-point is a very high cost method of assembling amplifiers because this method requires a lot of labour time and high skilled technicians. In return, the advantages of this method are the great durability and stable operation of the device so this method is often applied in producing high end tube amplifiers. Mavis’s all Tube Mosfet Transformer Amplifiers are assembled by point-to-point and this is an outstanding standard for the MAVIS’s hybrid tube amplifier.

ENGINEERING SOLUTION

– Driver Stage:

– The input and voltage amplifier stages use all 12AU7, EL84 tubes which are the best tube combination for the smooth, sweet and warm, emotional and natural sound. The voltage amplification using electronic tubes works in Class A Single-ended with an operation mode designed with a different mindset to combine the detailed, soaring sound of the first stage 12AU7 tube and the warm, seductive sound of second stage 12AU7 tube. The audio signal after passing through these stages is polished cleanly and smoothly.

– EL84 tube, a small power tube known for its distinctive warm sound, is used to amplify the current and control the power stage. Therefore, the sound is extremely seductive and emotional.

– Interstage Transformer (IT) and signal phase inversion is used to link the EL84 driver stage and Mosfet power stage. This way has the advantage of isolating the driver stage and power stage, making the stages operate separately and stably. IT is the optimal solution for the most stable and almost absolute balanced signal. In addition, using IT is always the top choice of experienced designers to achieve the finest quality of the musicality.

– Power Stage:

– Using Input-to-Output Balanced Circuit is the advantage of this design, which is excellent stability, low noise and very low distortion.

– To limit the reduction of signal by using too many components, only two Mosfets are used for the power stage circuit.

The sound is more clean and detailed when the speaker output is True Balanced, so the two speaker terminals (+) and (-) are not connected to the Ground (GND) of the power supply.

This amplifier uses true balanced outputs.

DO NOT connect the speaker outputs to ground under any circumstance.

A FEATURE OF SOUND MODE SELECTION

After a process of studying and experiencing real live music as well as through our research projects on amplifying the live music performances on high-end sound systems, recording and producing music, we find that music genres are really diverse and each genre will have its own characteristics of musicality and sound. In addition, depending on the culture, the specific music genre of each different culture, the listener has a difference in listening habits. Also, depending on the listeners age, music experience and personal favourite of music genres, the music need and sound taste of each listener will be different from the other. Indeed, each person will have his or her own needs in enjoying the music.

Accordingly, in addition to the sound that is reproduced properly and naturally by our sound philosophy and standards, some customization features are added to give the user an opportunity to choose the right sound mode to match the music genres, preferences, listening room conditions and combined devices to bring the most satisfying music experience to listeners. The users have complete flexibility to choose according to their personal preferences for their music and listening conditions.

Selection modes and sound characteristics:

– Standard & High Dynamic:

Standard	Standard sound mode has dynamic balance sound. This mode is suitable for most music genres.
High Dynamic	Sound mode is enhanced with high dynamics. This mode is suitable for epic music with fast tempo, strong like epic symphony, rock, the sound in action movies, etc.

– Soft Bass &Strong Bass:

Soft Bass	This mode is suitable for lyrical, gentle music, vocal music, non-drum instruments and is suitable for listeners who do not need a lot of bass.
Strong Bass	In contrast to Soft Bass, Strong Bass mode gives a fuller, deeper and more powerful Bass. This mode is suitable for epic music, especially those with the presence of large drums, most commonly found in grand symphonies played by the world’s leading large orchestras.
