For an inductor used in an audio circuit means that what the inductor "does" is dependent on the frequency of the input signals. That in turn means I, and I think everyone else reading this, cannot say much about the matter unbtill it's clearer what exactly you were working on. As well, are you sure you're not in some way mixing things up with transformer coupled
amplifier stages? That would make more sense. Especially since "louder" is not really a very good measure for amplifier quality comparison
(Cleaner is, "musical" is a very tricky one)
The circuit was an audio amplifier consisting of a single transistor stage to drive a single 12" driver. It was crude and far from ideal, but we made due with the parts we had to solve the problem. "Engineering" as it were. We plugged our iPods into the input of the amplifier, and plugged the output to the driver. No, not transformer coupled, we used the transformer primary instead of a collector resistor. Yeah cleaner doesn't necessarily mean better in audio, but in this case what I mean is with the collector biased using the resistor, the sound out of the driver was obviously lo-fi to the ear as well as noisy, and it was obvious that we were trying to squeeze wine from a stone. As it should be expected to sound with such a simple circuit trying to perform this task. With the inductor biasing the collector however, the signal was louder, less noisy, and seemed like it had a wider and flatter frequency response as well. It was obvious that we were able to squeeze a lot more juice out of this single stage circuit than we could before the inductor.
I know very well that this is not a gain stage that would be found in your average stompbox, but I do think maybe something could be gained from the concept. I remember tweaking the general idea of TS and Big Muff circuits to hell and back again, but I was very limited by voltage headroom for what I wanted to accomplish. With clippers that have forward voltages much higher than stock value, the signal would simply clip at the voltage rails of the gain stage leading to a terrible sound. If we build the gain stages out of transistors and feed the collector with an inductor, this should free up a ton of clean headroom to get a much wider voltage swing on the output I think. So the hope is that we can get away with using clippers with higher headroom and get a way more dynamic output tone.
Just something I'm thinking about. I'm probably wrong as usual
