After a few hours of conversation with Dima and discussing the Avicenna’s details I put the preorder transformers together and light up the Regenerator.  I was running it to different modes testing the operation and measuring the results in bypass, buffered and stabilization mode. I used different load from 1kw cooking pan to 1kW of my playback load, different loads, LC, CRC and any imaginable supplies. Well, this thing is made truly insulting it is even imposable to publish the sinusoid as in all modes with Avicenna engaged it outputs an absolutely perfect sinusoid with any load – there is nothing to see in the scope as it looks like came right from a reference generator. Dima said that at 500W load it has less than 0.1% distortion, so it is no surprise that I do not see anything in the scope. I will activate tomorrow the Avicenna distortion measurements functionalities and will be able to see them in real time.

So, I have a looks like perfectly operating, pure analog, unlimited power, over 85% efficient,  DC disabled,  regenerator with output impedance of a few milliohm and that out an absolutely perfect wave without any regard to load. Now I need to do what it is all about – to found out how it will sound. I did not listen Avicenna yet and it will be the task for my weekend. I am very glad what it does so far operational. The design looks like very very good, Avicenna shell be made commercially to show off how commercial equipment might be made with operational meticulousness of precision instruments.
