When ready, the PCB will allow for several versions, from simpler to more complex, at each stage. ;-).

Lavardin is not a normal amplifier, it is a constant power amplifier with the high end cut back because the tweeter impedance increases with frequency. This type of amp is outstanding in a car or simple crossover design speaker system.
the Zout of the amp can be calculated from the power out , it is not the .09 ohms stated in the pdf.

Where did you see that ? The aim of designer Hephaïstos/Gerard Perrot was to make the input and VAS stages driven by a transistor dissipating an almost constant power.
hello, forr
the audio review tests found
50w into 8 ohms , 51w into 4 ohms , 47w into 2 ohms. constant input signal

they also have there own spec sheet on their site.

Hi,
In fact power values are not measured but calculated from the applied voltage and the resistance load.
For the Lavardin datassheet numbers, they mean around 20, 14 and 10 Vrms of maximum voltage which can be applied to loads of 8, 4 and 2 ohms respectively. It does not mean that the output value in normal usage is constant power which, if so, would lead to uneven responses with loudspeakers.
There may be a trick in the circuit to get such numbers. This trick seems to have been modified, as you can check on recent technichal data published by the manufacturer : 55 W on 8 ohms, 110 W on 2 ohms.
