I found the time to go to Leipzig and use the [sublabs] oscilloscope on my [Diskokugel] circuit. Actually Nobody did that, assisted by Christian. It took a while to get it to work and the result was both satisfying and not satisfying. Because there was nothing to see. The crackle we hear when switching a speaker on and of did not show on the oscilloscope, which means the circuit works perfectly, and leaves us clueless as to the source of the problem. I did some more experiments but still have no idea.
Well, I might just leave it at that. Since the crackle is only really a problem when switching extremely fast or when a pure sine is used. I need to get this ball done now…
nothing to see here...
