This one just got traced over on FSB. Apparently the heaviest of Bjorn's Honey designs. Here's the schematic for reference. Note: In the schematic the source and drain on Q1-2 are reversed from the way they are normally oriented, but I recently learned JFETs are generally symmetrical and will work either way. The original is built on a PCB that several of Bjorn's circuits can be built with and is laid out for TO-18 package JFETs with a different pinout than the TO-92 packaged 2N5952. I'm wondering/guessing it was easier to swap the drain and source legs when fitting the transistor to the PCB, but perhaps other/earlier versions of the circuit used TO-18 JFETs and had the drain and source oriented the "normal" way. That's my reasoning and as a result I've reversed them to the "standard" orientation in this layout. Also I altered the polarity protection method to fit on the board better. I'll shut up now.
