The MAS600 split rear stage is a high-end model in the professional series of Raphaelite amplifiers. The single-ended electronic tube 300B has transparent sound quality and clear and charming lines. However, the power is limited and the speaker has been exhausted. For users who often listen to classical music and require comprehensive requirements, they love and hate it. The development of MAS600 is aimed at solving these shortcomings of single-ended. Taking advantage of our own transformer technology, we designed a permalloy transformer to drive two 300B inverters with a push-pull output of 25W. With 300B's low internal resistance and no large loop negative feedback circuit, the whole machine has excellent transient control power far more than several times that of crystal machines. The transformer coupling also retains the single-ended sound quality and the transparent lines are clear, and the sound is charming but there are Wider speaker adaptability.
main feature:
● The left and right channels are separated independently and have plenty of power.
● Permalloy transformer phase inversion, semi-self-contained semi-fixed bias circuit.
● Full electronic tube rectification, high voltage buffer start.
● All imported electronic tubes, 300B use Golden Lion brand.
● Current level detection and display.
● The fully coupled output transformer has multiple output impedance options.
● Suspended ground circuit, ultra-low noise, suitable for quiet listening of various high-efficiency horns.
● Fully shielded steel case, strong frame structure, safety net cover, imported aviation aluminum wire drawing panel, and heavy aluminum handle.
