from their website.
together with the regular guts this should be an easy one. Anyone take a shot? I'm not really interested in tracing a JFet Boost.

Ah, so you're too good to trace it, but the rest of us troglodytes' time is so invaluable that we should do it?
Just kidding.

I'm triyng to trace it right now, but can't figure out the circuit. If anybody is willing to help, here's the trace + component side. Will post a preliminary schematic later

hmmm
it's two identical jfet boosts that the cascades via a switch.
could be
this?
edit: close but it's similar. Will update the values of the resistors soon.

here they are. too bad i couldn't read the tant caps, not even from the side shot. The power supply cap looks pretty big, maybe a 47uF?
Not sure about the transistor, a J201 would work though.
