Today I am tired and my mind feels dull and quite worthless.
I have been thinking about a "Concertina" split load phase splitter based amp with a bifilar winded choke as load.
I ended up with the circuit above, and it works nice. I am playing Melody Gardot March for Mingus as I type this.
I can't say that I am impressed by the sound in any way though.... There is nothing wrong really, its just a bit dull and boring to listen to.
The same IRFP7430 in a Zen type amp sounds marvellous with abundant muscle and joyful vividness.
Is the transformer-core magnetized in the above schematic? I can't grasp this circuit today. What could be the reason it sounds so dull?
I tried to couple the two windings differently and the music just disappeared, so I guess that was the wrong way.
Thankful for any comments on this, since my brain is on sick-leave today, an just flat out refuses to do anything meaningful...
