[Features]
◎Pure Class A operation, 100W/8Ω high quality power
◎Two completely identical power amplifier units are driven in parallel.
◎Output stage has 20 "power MOSFET" parallel push-pull configuration, achieving linear high power down to ultra-low impedance of 1Ω
◎The input section uses a double-configuration instrumentation amplifier system.
◎Equipped with "Double MCS+ circuit" and "Current feedback amplification circuit" in the amplifier section
◎The output can be further increased by connecting two A-250s in a bridge.
◎Powerful power supply section with highly efficient large toroidal transformer and large capacity filter capacitor
