Lab12 integre4 Mk2 Toroid Version (KT150) Integrated Amplifier
The integre4 Mk2 Toroid Version is Lab12's flagship integrated amplifier, running KT150 power tubes from the factory for 65 watts per channel and a genuinely low noise floor for a tube design.
A true dual-mono layout uses two separate high-current toroidal transformers with fully upgraded dual power supply stages, and a built-in bias system with a processor-driven OLED display lets you tube-roll (EL34, 6550, KT88, KT120, or KT150) and dial in bias directly from the front panel, with no external equipment needed. An OTL-style headphone circuit shares the same upgraded power transformers, and an optional tube cage is available for extra safety.
