The Yaqin MS-6V6 amplifier is a tube amplifier working in a down-pull system based on very popular stream tetrodes, 2 medium power 6V6 (6P6P) lamps per channel and 2 control lamps (1x12AU7 and 1x 12AT7) per channel.
The main advantage is the total maintenance-free (autobias), headphone jack, gain control with remote control, cheap and available lamps.
Suitable for reproduction of any musical genre, showing its charm in small musical compositions. It gives a clear and deep scene with a true picture of warm tube sound. It will drive most of the speakers without any problems. Soft bass, pleasant to the ear, high tones very clear but not exaggerated. He calmly copes with the 30m salon sound system.
The amplifier uses a system that protects the tubes during the start procedure. After switching on the supply voltage, the amplifier goes into the mute state. For several dozen seconds, the filament voltage is applied to the lamps, then anode voltage is applied to the input lamps. After a few seconds, the anode voltage is also applied to the output stage, and the amplifier goes into standby. The power supply of this amplifier uses separate power transformers, chokes and filters for individual stages, enabling their complete isolation. High-capacity capacitors were used in network ripple filtering systems.
The design uses transformers from STALLOY, high-quality metallic resistors, selected electrolytic capacitors. Everything is placed in a solid aluminum housing. The protective cage for power lamps is also made of aluminum.
The front panel has a headphone jack and 4 input selector switches. A potentiometer knob is located on the side panel. Gain adjustment is also carried out using a remote control that starts the servo mechanically connected to the potentiometer.
On the back of the amplifier we have 4 RCA inputs and 4 and 8 Ohm loudspeaker outputs. On the side wall of the housing there is an output selector switch.
