Default Front Panel Help

I have reached the point of front panel assembly where the modifications are needed (jumpers, capacitor, resistor). From the pictures, I'm having trouble seing exactly where to make the connections. Could someone provide a text description of where these components should be installed?

I'm not very good with words! Lets try some high resolution pictures first!

The capacitor is .1uf, the resistor is 10 ohm, Brown Black Black

If after these you still have questions, please ask...

ONE cut trace next to R31

TWO cut traces

Thanks Grant,

I think the glare coming off solder points was making it difficult to see on the lower resolution printed pics. Those higher resolution pics helped.

Specifically, I was having trouble seeing if the connections were made to more than one solder point (they are not). Also, I couldn't tell that one end of the jumper, and one end of the resistor, are directly attached to an end of a broken trace.

Thanks for the clarification.

One observation about the front panel: on pages 8 & 9 of Grant's instructions where he talks about placing nuts on the switches before installing the LEDs to get the correct front panel spacing, the photograph shows one nut on each switch but you really need two if you're going to use the little conical trim nuts after the panel is installed.
