Description

This mono power amplifier uses a bipolar LAPT (Linear Amplified Power Transistor) element with a current supply capacity of 17 amps for continuous operation and 34 amps for instantaneous operation. The power amplifier module is a three-stage Darlington configuration with 6 parallel push-pull bipolar LAPT elements. The two-module configuration mounted on two large aluminum die-cast heat sinks improves heat dissipation efficiency and stability. The power transformer uses an ultra-large toroidal core transformer with a mass of approximately 18 kg and a core size of 3,057 VA. A fully balanced input stage is used, and a dedicated input buffer amplifier is provided for each input system (RCA x 1, XLR x 1). The signal path up to the amplification stage is transmitted with low impedance and full balance, eliminating common mode noise. The signal path is also less susceptible to noise. The chassis is a traditional Esoteric two-layer structure. The robust internal structure of 2 mm steel plate has dedicated compartments for each circuit block. The bottom chassis is made of 5 mm thick steel. The front panel is machined from 35mm thick aluminum. The legs are supported at four points by pinpoint feet.
