  • Notes
  • Continuous Average Power Output (C.A.P.O.) both channels driven:
    Load                    C.A.P.O.                              Distortion
    8 Ω                          250                                  0.025 THD
    4 Ω                          375                                  0.025 THD

    Frequency response 20 - 20,000 Hz, for 250 Watt per channel at 8 Ω and 375 Watt per channel at 4 Ω.

    This amplifier can be equipped with two power transformers, to have the possibility of operating at 120 or 240 V. It is also equipped with two thermostats one for every channel, that at a temperature of 100° C cut off the power supply.
    The power supply voltage of 80 V DC is supplied by 2 rectifier bridges, one for each channel, delivering each a current of 25 A. The voltage for the LEDs is supplied by a pair of diodes independent from the power supply of the amplifier circuit.

    29 transistors, 7 ICs, 18 diodes, 1 Zener diode, 2 rectifier bridges, 2 rectifier diodes, 28 Leds, named one per type and not all.
