LayoutBuilt this one, and had the very low output issue that someone else had - almost no output.
Checked pots, all component values, replaced a couple of resistors for good measure.
Knifed strips, checked continuity, everything seems okay.
Tried different transistors, tried JRC4558, RC4558P, TL072, no luck.
Pulled ICs and Transistors from working builds that I know worked, still low output.
Maybe someone can find something I've missed?

EDIT: in case anyone is wondering, the 47u cap *is* oriented correctly (as are the others) - the marking just makes it look incorrect.
