I ended up with a custom made preamp or compressor of some sort, but it doesn't really look quite like any other preamp or compressor I've seen, doesn't quite act like one, and has some really strange inputs/outputs. Audio inputs/outputs are a 1/4 "mic" input (with in/out switch and gain knob) and stereo RCA inputs and outputs. And it has 2 power cords AND a power outlet on the back! I opened it up and it's just unbelievable inside: the main PCB is done with components placed in IC sockets on the board, and then the points are connected on the underside by dozens of tiny, tiny wires! And they're not soldered; each end is tightly wrapped around the legs of the sockets!
So I'm trying to figure out what this thing is, and use it as an opportunity to learn about components, symbols, how schematics work, etc. I'm just tracing the wires from component to component and drawing it using the appropriate symbols and values, etc., but my "diagram" is getting really messy.
Are there any good starting points, conventions, etc. that might help me make a more sensible schematic? For example, everything that's connected to the black wire - can that stuff just go to the ground in the diagram, or does it have to go back to the power?
I suppose that most schematics are laid out with appropriate groupings, i.e., a timing circuit together, a filter circuit together, etc. Since I have no idea what I'm looking at, I can't really do that.
When I get this schematic done I'm going to post it, along with pictures of this thing. Hopefully by then I'll figure out what it's supposed to do!
