Here’s another circuit I ran across will going through the Free Information Society site. It’s designed by Jamie Heilman and seems to be like if a Distortion + and a germanium fuzz had a baby. The first stage uses a single op-amp (NE5534 in the original, but others could be used–TL071, LM741, etc) that pushes as single PNP germanium transistor. The orientation of that transistor confuses me and makes me wonder if it should be an NPN, or a PNP flipped 180º. Here’s the schematic so you can share in my confusion. So socket the transistor and experiment. I’ve added the small capacitor in the feedback loop referenced in the schematic notes. Add it if you have some extra noise. This one should easily fit in 1590a.
I don’t have a demo of this circuit, but I thought people might get a kick out of how I layout these circuit boards. It’s not really a tutorial, but you can get a feel for how I make my layouts. I use DIYLC and then Photoshop.
