M10S is a single ended Class A tube integrated amplifier, it can use 6550 and swapped to EL34 and KT77 only by re-biasing actually. As a mini size integrated tube amplifier, there is one feature which distinguish the Cyber 10 with similar pentode SE amp which use a self-bias circuit, M10S incorporate a fixed bias design for easy tube swap and more power delivering as well. Single bias adjustment mechanism for each output tube has been equipped inside chassis, a trim pot for adjustment to get to 0.4mA bias current. The bias adjustment can be measured by a voltmeter (not come with the amp). While the output tube is operating with in Ultra linear mode to give 12W output power, there is also a switch to operate the amp in triode mode which halves the output power to 6W.
On the other hand, you could use M10S as a heavy design tube headphone amplifier with output transformer which can easily adapt to headphone having impedance ranging from 10 to 600 ohm. One 3.5mm jack and 3 RCA inputs have been equipped behind of chassis. Selectable and volume control is remote-able as well. |
