PLEASE NOTE! The 1/4 watt 5% resistor R35 (470K) is located on the front panel and not on the printed circuit board.
See the "Case Wiring" page for details.

PLEASE NOTE! I highly suggest that you install the components onto the PCB in the following order:

The Kludge Experiment area is for your contribution to Weirdsoundology. It is the fertile soil of discovery. It is the last true place of innovation on earth. It is... some extra area that I could not bear to let go naked. Hey benders... let's see whacha got!

MFOS Weird Sound Generator Populated PCB

The electronic components that come with your kit may not look exactly the same as the parts shown in this picture. That's OK! All the parts that come with your kit will have the correct values and that is what matters. When you lay out your parts to check that they are all there you want to be concerned with the values not the physical appearance. The resistors will look very similar but the capacitors may vary in appearance. The 1/4 watt 5% resistor R35 (470K) is located on the front panel and not on the printed circuit board. See the "Case Wiring" page for details.

Andrew did not include C9 and C10 battery power supply high frequency noise bypass caps. They are not necessary but are typically included in designs to provide high frequency noise bypass. If you want to include them just wire them across the plus and minus power pins of each IC.
