This Class A/B stereo power amplifier module, sold in kit to assemble and weld, is made of discrete components and can develop a power of 2x 125W under a 4Ω load and 2x75W under an 8Ω load. Specially designed for audiophile applications, it features high-quality components: two JRC5532D low-noise dual AOPs coupled to TL431 voltage regulators, two TI TL071CP dual OPAs, two pairs of Toshiba 2SA1943/2SC5200 power amplifiers and two pairs of A1930/C5171 transistors.

The first two OPA5532s do not have a traditional AOP function; they are there to receive the input signal. The TL0771CP OPAs act as preamplifiers, before the signal passes through the power amplification stage comprising two pairs of Toshiba 2SA1943/2SC5200 transistors. Two output inductors then process the signal to slow down surges and current peaks, to clean the signal of high-frequency noise and to correct the phase shift of the high-frequency crossover capacitors in advance.

The module's power supply accepts voltages from 15-0-15V to 30-0-30V AC.

Audio signal input is via screw terminals. Thanks to these two screw terminals, two configurations are possible. The module accepts an unbalanced RCA signal (AUX) as well as a balanced XLR signal. A switching relay and a button are used to select the source mode.
