using AUC logic and smaller components
C2: 0.047u for ~3.5 kHz, 1u for ~170 Hz
C1, C3-C9: 10u
R1: 6.8kohm
R2-R6: 220 ohm, lowest inductance possible (ERA-1AEB221C used – 0201)
U1: 74AHC1G14GW,125
U2-U7: SN74AUC1G17DCKR
In my build I added a 220uF electrolytic at the power input and added additional 0805 bypass caps directly across the power and ground of each gate (actually power and NC pin, as that is grounded).
