- C2 are on both the components and the panel PCB. To better discern between both of them, in the detailed build document they are labelled as C2 and C2POTS (step 26/45)

|
- C3 should be styroflex or mica (it should be relatively accurate and stable regarding temperature changes).

| 1 | Change the oscillators frequency range by using a different value for C3 (Step 27 in detailed manual). Increasing the value lowers the range. A Value of 2.4nF should create a range from ~0.5 Hz to 15kHz. Make sure to use a stable cap here (Styro, Mica, ...) to avoid drift. | Sorry no pic :frowning2: |
