Lab12 suono Mk2 Toroid Version (KT150) Class A Power Amplifier
Suono is Lab12's smaller single-ended Class A amplifier, delivering 25 watts per channel with KT150 tubes for an intimate, emotionally engaging listening experience the brand describes as their most lovable amplifier.
A powerful low-noise toroidal transformer feeds the circuit, and bias adjustment is directly accessible on the top cover, with no need to unscrew anything to check anode current. Like the rest of Lab12's Class A power amps, it offers a switch between Triode and Ultra Linear modes.
