@Boswell @pcrecord (or anyone else who might be able to help) Hi guys So, lets say I have a little more than just a passing interest in perhaps building an opto compressor from a kit...and I want to start by familiarizing myself with basic electronics knowledge. Is there a good textbook I should start with to gain a greater understanding of what it would take to be able to build gear from a kit - similar to what Marco did with his new mic? Or does that sort of project require advanced skills? I don't mind putting the study time in, and realize that this knowledge won't come come in just a few days, or even weeks... Would there be an easier audio kit project - other than a mic or compressor - that I could start out with to get my feet wet? Something that, if I totally screw the pooch on, wouldn't be a "oh God kill me now" kind of price mistake? Thoughts? Thanks.
