This hybrid power amplifier Santor with its wide class A area and its capability to produce high current is despite its seemingly low output power, able to reproduce dynamic jumps and micro information accurately. The number of amplification stages in the signal path is reduced to a minimum as in all AcousticPlan components. The signal for voltage amplification passes only one triode responsible for the sound quality of the Santor power amplifier followed by a tube driver and finally an impedance converter with MOS-FETs. This is done without any overall feedback or differential amplification. Balanced as well as unbalanced inputs are transformer coupled to achieve DC free signals at the first stage and groundless connection with balanced signals.
The Santor stereo power amplifier can be converted into a mono power amplifier in bridged operation for high power output. Therefore, phasesplitting is provided by the transformers.
The casing consists of high quality, precision-engineered single aluminium plates and two heat sinks placed at the outside. The main transformer is enclosed in a separate unit.
