So according to the thread over at FSB there's no mention of the specific JFETs in the original other than they're N-JFET. It's possible they're either BF244 or 2N5952 both of which Bjorn is known to use. So I decided to make 2 layouts, one with a DGS pinout (BF244) and one with DSG (2N5952) so either can be made. There is also a question as to whether or not the 47k resistor going from Drain of Q1 to the power rail actually being 14.7k like the drains of Q2 and Q3, so as of now if you build this you may want to socket that resistor so you can try both and see which sounds better.
