[sdiy] (2) SH-101 help

[media at mail1.nai.net]

Mine shows a 1K restistor going from the op-amp's output.

The op-amp with VR2 (9a) is on one side of the mux, the op-amp driving the
CV out (9b) is on the other side, although I'd assume they are in the same
package.

Frankly, I don't get the mux, the range circuit makes sense, but according
to the schematic, it looks as though the internal CV and CV out would not
be available at the same time.
