Forty-two watts per channel, Class AB Integrated Stereo Amplifier with KT88 (JJ Electronic) output power tubes, 6CL8A (Mullard) and 12BH7 (Electro Harmonix) input tubes.

LM-88IA Amplifier can operate in two different ways Auto-biased or Fixed bias. You can select the one you prefer. Power output for Auto-bias mode is 45 watts while for fixed bias it is 30 watts per channel.  

Specially designed Toroid transformers made of Z11 Core fort power supply and two Japanese Audio grade EI types of output transformers with wide bandwidth are applied. All transformers and chokes are encapsulated and installed separately on the amplifier to avoid and lower the disturbance between each other.
