555 Class D Power Amplifier UPDATE
Update of my 555 Class D power amp.
About 10 years ago, I published a class D amplifier built around the good old 555 timer - Elektor 130144 I now have made some improvements on the original design.
The "non perfect" voltage to current convertor is updated to a better FET version and I have add an input FET buffer.
I have used this amplifier in my living room all this time, next to a Menno Vanderveen UL40 tube amp as a reference, to the point where I can't hear any difference between both.
Both amps run without any overall feedback, what makes them so great in my opinion!
