http://crazyyellowfox.net/tl072sectlayouts.pdfI feel like I'm beating a dead horse here with this topic, but I finally got around to building this thing and
I'm amazed at how good a three-transistor op amp can sound. I wanted something a little cleaner than
my poorly perfboarded version of this, so I drew up some layouts. One for each section of a dual op amp.
You might be able to squeeze both into a single dual op amp socket, but it'll take some cramming. The "A"
section is a little more compact than the "B" section. I made the "B" layout as well because I have some
older boxes that I perfboarded using the B side of a dually that I'd like to play around with.
Something I found tinkering a bit... low gain PNPs sound really good with a high gain NPN output transistor.
