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

P200 is a Power Amp designed with strong internal power to be an incredible partner for difficult loudspeakers in order to achieve a very detailed and sophisticated sound.

– This model is optimally engineered using famous electronic tubes CV-181 / 6SN7 / 6H8C for voltage amplifier stage and phase inverter to make the sound emotionally warm, detailed and highly musical.

– The Driver stage uses a 6V6 power tube and a Single Ended – Class A Interstage Transformer to optimally convey the flexibility and sophistication of the tubes to the MOSFET power stage.

– The use of OUTPUT Transformer combined with power MOSFET at the Power stage gives the P200 a unique sound quality of tube amplifier and the highest dynamic level of zero feedback solid state amplifier, thus creating the P200’s extremely large and explosive soundstage.
