Like the entire range of Kora amplifiers, the TB140 is powered by the Square Tube® operational amplifier. Equipped with 4 triodes per channel, this innovative assembling gives all its qualities to the amplifier.
SquareTube® provides every amplification functions. Its output voltage is the one that will be applied to the speaker outputs. Audio power transistors, exceptionally linear, are the only ones to provide what technicians call “impedance matching”. The transistors will give the speakers the required current, without amplifying the signal.
Their role is somewhat the same as the one generally assigned to the output transformer.
However, the SquareTube® / Transistors’ combination does not know the difficulties associated with the usual transformers:
The combination of SquareTube®’s high voltage capacity and the high current of the output transistors gives you an unmatched high definition power amplifier.
