So in short, i need to mutiply the voltage bij 1.2 with a class A amp? (language barrier haha)
If i understand correctly it is because of the constant current draw of the amp?
Would it be possible to use a transformer with 20v or 22v windings? Can not get a 21v overhere.
22x1.2 would be 26.4v...to high? (using chokes etc. in power supply)

The supply voltage, within a few volts, wont really affect the performance, the bias current will.
The higher you go with supply and bias the hotter the amp will run requiring much bigger heatsinks.
If you compare the Alephs you will see increasing numbers of output MOS-FETs to accommodate increasing rail voltage, bias and output power.

Thanks venerable friends, Dr Hal say that we can find the sweet point with each component. In this case with the A3 is possible to establish which is this point where the distortion going down by a 90% factor. I am intrigued with the original article and probably this point that anybody look for maybe some of us could know or could determinate in their bench.
