Hello.
I've been doing electronics on-and-off since I was five. I'm in my fifties now. I studied it at university but dropped out. Over the years I've designed and built a few projects, like a neat linear capacitance meter idea using op-amps (sadly I no longer possess it, or the circuit diagram). I've built a couple of amplifiers too. My first one consisted of a 2N3055, a loudspeaker, a 5k pot, a capacitor and a 6V battery. Nothing else! It did sound quite nice too, but the standing current through the speaker probably wasn't a good idea... Then I made one with an LM380 chip. It worked better but sounded worse.
A few years ago I developed a chronic condition which means now I'm stuck in bed and can't really do much without getting exhausted. Recently I remembered a funny idea I was playing around with for a MOSFET power amplifier design with more than five components. I had abandoned it previously, but still had LTSpice files, so started looking at it again. I won't bang on about it here, but I'll start a thread about it in due course.
Obviously, one thing leads to another and now I have an interesting design which seems to work in the simulator. I'm certainly not an expert although I suppose I'm quite knowledgeable in some areas. Recently I picked up Doug Self's Power Amplifier Design, which is great and quite useful. But of course during the design process, many questions arise that aren't mentioned in books, and even Google doesn't want to tell me about.
This site kept popping up though, and it looks good. I was quite reluctant to join a community (I'm not really a "people" person, and I don't need to tell you about the reputation that audiophiles have, hehe) but after perusing the pages I came to the conclusion that at least not everyone here is insane, so maybe it might work out.
So I guess I'll have some questions later on, and in a while I'll share my ideas too.
