- | 4. Continue with the yellow **ceramic capacitors** marked as 470 (47 pF). These will help to protect the circuit from very high frequencies beyond the audible range and oscillations. These are not polarity sensitive.</ | + | 3. Continue with the yellow **ceramic capacitors** marked as 100 (10 pF). These will help to protect the circuit from very high frequencies beyond the audible range and oscillations. These are not polarity sensitive.</ |

- | 6. **Now you can solder in the 4 pink polypropylene capacitors.** These will limit low frequency pick-up. These capacitors are also not polarized. Also if you decide that you would like to have bit more bass, you can replace these with higher values (for example 10 μF instead of 2.2 μF).</ | + | 5.
